Want to Attract Pollinators? Easy Fix for Sunny Yards

Pollinator plants surround a small grassy area in my front yard. In the forefront (back row, r to l), you’ll see little Trudy catmint, orange carpet hummingbird trumpet and Mojave sage. In the front row, going counter-clockwise, you’ll see dwarf broom (scruffy blue shrublet), Pawnee Buttes sand cherry, Sonoran sunset hyssop, sunset hyssop, autumn brilliance serviceberry, Rozanne cranesbill, tiger eyes sumac, more Sonoran sunset hyssop and Karalee petite pink dwarf whirling butterfly (a new Proven Winners annual).

When I headed out my front door this afternoon to pick up my mail, about 20 painted lady butterflies fluttered up from my flowers and began flitting around me.  I felt like Snow White in a Disney film!

Granted, there has been an unusually high number of painted ladies along Colorado’s Front Range this year.  I’m just delighted a small flock of them decided to visit my garden.

Don’t forget annuals when planting for pollinators. This Salvia farinacea is a huge hit with bees and butterflies. Notice the painted lady butterfly at the top of the tall spike on the right.

Nearly every plant in my front yard is a nectar source.  And some of the plants, such as butterfly weed, serve as butterfly hosts (egg-laying sites and larval food sources), as well.  Which only goes to show that your garden doesn’t have to look like a weed patch to attract pollinators.

Since installing all these plants, I’ve noticed that my yard has turned into a virtual pollinator factory, with buzzing and flitting going on throughout the day.

What are some of these critters’ favorite meals?  Well, bees go gaga over little Trudy catmint (Nepeta ‘Psfike’ Little Trudy). Hummingbirds and butterflies, meanwhile, feast on sunset hyssop (Agastache rupestris), Sonoran sunset hyssop (Agastache cana ‘Sinning’) and orange carpet hummingbird trumpet (Zauschneria garrettii).

It’s important to ensure you have flowers blooming throughout the growing season to provide a continuous food source.

So in the spring, my serviceberry (Amelanchier x grandiflora ‘Autumn Brilliance’), Pawnee Buttes sand cherry (Prunus besseyi ‘Pawnee Buttes’), Cheyenne mock orange (Philadelphus lewisii), dwarf broom (Genista lydia), ornamental onion (Allium ‘Globemaster’) and soapwort (Saponaria ocymoides) provide sustenance.  Little Trudy begins blooming in early May and keeps going till frost.  Rozanne cranesbill (Geranium ‘Gerwat’ Rozanne) blooms in May, as well, and will keep blooming into fall if you cut it back when it starts fading in late summer.

Small but mighty, this Miss Molly butterfly bush from Proven Winners adds a glorious touch of fuchsia to the garden while feeding butterflies and other insects. This shrub will eventually grow four to five feet high and wide.

Then in summer, lavender (Lavandula angustifolia ‘Munstead’), butterfly weed (Asclepias tuberosa ‘Hello Yellow’), orange carpet hummingbird trumpet, hyssop, Stella d’Oro daylilies, butterfly bush (Buddleia x USPP 23423 ‘Miss Molly’), Pollypetite rose of Sharon (Hibiscus sp. ‘Rosina’ USPPAF) and snapdragons (Antirrhinum majus in my side-yard rock meadow) generate blossoms.  Except for lavender and butterfly weed, all of these summer bloomers keep generating flowers well into fall.

And, of course, I have annuals blooming in pots and in the ground to provide yet another food source.

Long-blooming orange carpet hummingbird is one of the top two plants in my garden for attracting hummingbirds. The other top hummingbird plant is agastache.

Granted, I have a few plants that pollinators don’t visit for food.  There’s my Kentucky bluegrass, for example.  It doesn’t produce nectar, but it does provide a runway, which butterflies and hummingbirds appreciate for zooming around.  My tiger eyes sumac isn’t a food source either, but its dense foliage can provide shade and storm shelter for pollinators.  As for my groundcover roses, they don’t produce nectar for pollinators, but bees will visit them to collect pollen.

In my rock meadow in the side yard, pollinators can feast on snapdragons, daylilies and columbine, as well as soapwort and prairie winecups. The potentilla in the upper right will be removed soon as part of my efforts to install a large pollinator garden near the back yard patio.

Besides food, host plants, shelter and runways, pollinators require water.  A shallow saucer filled with sand and water will enable butterflies, for example, to rehydrate themselves and ingest important minerals.

If you don’t have many pollinator plants in your garden, consider planting more next year.  You’ll be surprised at the difference they make.

PWs’ Lantana & Double Calibrachoa Rank Among Favorites for 2017/2018

The blooms of Luscious Royale Cosmo lantana emerge in pink, yellow and coral before turning into a gorgeous magenta set off against deep green leaves.

I’ve always considered lantana to be a gaudy, cartoonish flower that has no place in my yard or pots. This plant often exhibits unappealing color combinations, such as white/yellow, orange/yellow, or weird, faded shades of legitimate colors. If you do a lantana image search on Google, you’ll see what I mean. So in spite of the fact that lantana is supposed to be a stellar performer, I’ve never given it a try—until this year.

In May, Proven Winners sent me some new plants to try out, including Luscious Royale Cosmo lantana. This variety has been a game changer for me. I discovered that the blooms, which start out as yellow, coral and pink, mature into a rich magenta set against deep green leaves. And talk about performance—on my south-facing front walk, this plant blooms consistently with no sunburn. This outstanding variety will be available in garden centers in 2018.

I’m thinking that perhaps growers photograph lantana blooms in their early stages to show all of their colors, rather than showing them at a later stage, when one or two dominant colors may be richer and more appealing.  So unfortunately, the early photos may not do the plants justice.  And of course, when we visit garden centers, we usually see plants that haven’t yet matured.

Superbells Double Ruby calibrachoa hybrid’s luxurious double blooms brighten any outdoor flower arrangement. This darling will be available in 2018.

Other standouts in Proven Winners’ lineup of annuals include:

  • Superbells Double Ruby calibrachoa hybrid. This calibrachoa boasts double blooms that resemble tiny carnations. Mine has grown 4 inches high and 2 feet wide since early June. It’s delightful.
  • Superbells Blue Moon Punch calibrachoa. Another solid performer, this cheerful charmer pumps out purple and white blooms with a brilliant yellow throat. Mine cascades down the pot about 16 inches.
  • Prince Tut dwarf Egyptian papyrus. This fast-growing, no-maintenance stunner has reached two feet since I planted it in a pot in early June. It reportedly will reach 30 to 48 inches at maturity.

Proven Winners’ Pollypetite dwarf rose of Sharon produces ethereal pink blooms.  It reportedly grows 3-4 feet high and wide.

In Spring 2018, Proven Winners will introduce a new rose of Sharon, Pollypetite, in garden centers. An endearing shrub that grows 3 to 4 feet high and wide, Pollypetite features delicate pink, iridescent blooms.  Because of its smaller size, this plant will fit nicely in gardens that don’t have room for typical roses of Sharon, some of which can grow 10 feet high and wide.

Eye-Popping Blooms Abound at High Country Roses Near Denver

You can easily drive right by High Country Gardens’ entrance, if you’re not looking for it.

High Country Roses’ humble little road sign can be deceiving. But make no mistake; it marks the entrance to one of the finest rose nurseries in the country.

Six years ago, this family-owned company relocated from Jensen, Utah to Arvada, Colorado. So now it’s within spitting distance of Denver, Longmont, Fort Collins and other communities along Colorado’s Front Range.

High Country Roses’ customers include the Denver Rose Society and Denver Botanic Gardens. That should tell you something about the quality of HCR’s plants.

During a tour of High Country Gardens’ growing facilities, employee Dare Trotter stopped to show me a Livin’ Easy rose.

As for the prices—they’re surprisingly reasonable. Most roses currently cost about $15 to $18 apiece, not including shipping. If you make an appointment to pick the roses up, you can skip shipping costs altogether. Compare that to $40 per rose (usually grafted) at other nurseries.

Granted, HCR roses come in one-quart pots, which are smaller than your typical $40 rose pots. But these babies are extremely healthy, and they grow quickly.

Better yet, HCR’s offerings are own root roses, not grafted roses. With own root roses, the flowering top of the plant is the same as the root. But with grafted roses, the flowering top of the plant is a different variety from the root stock, which is typically a hardier, but less desirable variety.

Deb Lynch keeps roses healthy by making sure they’re watered appropriately.

Why is this important in Colorado and other cold winter climates? A very hard freeze may cause the plant to die down to its roots. But if the plant is an own root rose and it regrows, it will return in its original form. For example, an own root Mr. Lincoln rose will grow back as a Mr. Lincoln.

With grafted roses, on the other hand, a very hard freeze may cause the plant to regrow from the less-desirable root stock rather than from the desired top stock. So, for example, if Mr. Lincoln is grafted onto Dr. Huey, you may end up with a Dr. Huey rose after the freeze.  To reduce the chances of this happening, it’s advisable to plant grafted roses so that the bud union is one to three inches below ground in cold winter climates.

High Country Roses took root in the basement of Dr. Bill Campbell’s urology practice at 17th and Downing Street in Denver. A rosarian and surgeon, Dr. Bill founded the High Country Rosarium in 1970, after spending a decade collecting and testing varieties of old garden roses to see which ones would perform best in Colorado’s harsh climate.

In 1995, the company moved to Jensen, Utah, before returning to the Denver area in 2011.

Although HCR is primarily a mail-order nursery, Dare Trotter and Matt Douglas have been assembling a few orders for local pickup.

Dr. Bill has since passed away, and other family members have helped keep the business going. Now Dr. Bill’s stepson, Matt Douglas, manages the business. Matt and employees Deb Lynch and Dare Trotter comprise HCR’s production crew, which handles the propagation and maintenance of 350 varieties of roses.

What are some of these folks’ favorite roses? Matt likes Golden Wings. Deb prefers Ebb Tide, Angel Face and Livin’ Easy. As for Dare, he likes Distant Drums and Cecile Brunner.

Me? I’m a huge fan of Linda Campbell, a gorgeous red repeat-blooming rugosa rose.

So if you’re in the market for roses, you might consider ordering some HCR roses and making an appointment to pick them up, if you live close by. Otherwise, you can have them shipped to you.

Asclepias: Mother’s Milk to Monarchs & 2017 Perennial Plant of the Year

Perennial butterfly weed, Asclepias tuberosa, serves has a host plant for the monarch butterfly by creating a site for the mother to lay eggs and for the larvae to feed. (Photo courtesy of Dave Powell, USDA Forest Service - retired, Bugwood.org.)

If I wanted to attract butterflies and had room for only one nectar plant, I would choose butterfly weed (Asclepias tuberosa).

Butterfly weed is not only a terrific nectar plant for many butterfly species, but is also the sole host plant for the monarch butterfly, whose numbers have been decreasing so steadily that they’ve reached “Near Threatened” status with the World Wildlife Fund (WWF). In cold weather, monarchs migrate between more than 1,000 miles between the U.S. and Canada to forests in central Mexico, where they hibernate until it’s warm enough to head back north. Earlier this week, Omar Vidal, CEO of WWF in Mexico, issued a statement urging the eradication of illegal logging in Mexico’s forest cover and asking that habitat loss be tackled in the U.S. and Canada, as well.

In the meantime, the Perennial Plant Organization has selected Asclepias tuberosa as its Plant of the Year for 2017. Shoot, they’re even selling tee shirts to promote this North American native!

With its striking, deep-green foliage and vibrant orange blooms, butterfly weed is a real showpiece in the garden. It grows 12 to 30 inches tall. There’s a newer, yellow variety called ‘Hello Yellow.’ I planted one in my garden last summer, and it lasted till frost, when it went dormant. I’ll see if it emerges this spring.

Several Colorado gardeners have told me they’ve been unsuccessful in growing butterfly weed in our heavy clay soils. Anticipating problems but being curious, I bought a #1-sized plant from a local nursery about five years ago. I amended the soil with organic matter before installing this beauty, and, surprisingly enough, the plant seemed very happy. It popped up reliably the following season.

For those of you who haven’t had luck with butterfly weed, I have a few suggestions:

  • Install a healthy, #1-sized plant from a reputable nursery. Smaller plants don’t seem to establish as well, according to some of my fellow gardeners.
  • Be aware that butterfly weed has a tap root, and if you damage it in any way, the plant will die.
  • Amend the soil if you have heavy clay. I used compost. Another experienced Colorado gardener suggested using sand or gravel for amending. Good drainage is critical.
  • Wait until drier weather to plant it. In other words, don’t plant it in the spring, when there’s more rain. Wait until a summer month.
  • Plant your butterfly weed in full sun.
  • Keep a close eye out for yellowing leaves. If you see a lot of yellowing, you may be over- or under-watering the plant. Over is more likely. Asclepias tuberosa doesn’t like too much moisture. If you can nurse your butterfly weed through its first growing season, you may be home free. Fortunately, the plant spreads nicely, once established.

    Annual butterfly weed, Asclepias incarnata, offers stunning pink, mauve or white blooms. Be careful where you plant it, though, because it reseeds prolifically. (Photo courtesy of Rob Routledge, Sault College, Bugwood.org)

There’s an annual butterfly weed, Asclepias incarnata or swamp milkweed, which also serves as a host for the monarch. Swamp milkweed grows four to five feet tall and produces white, pink or mauve blooms.

If you would like to learn more about butterfly gardening, you’re invited to attend my free program, Butterfly Garden Basics, at the Loveland, CO public library, 300 North Adams, on March 29. The program begins at 1pm. Arrive early, though, because I’ve been told that 50 or more people often attend the gardening presentations at this library.

Transform your Shady Rock Meadow into an Ocean of Color

Plumbago's gentian blue flowers, copper seed heads, deep green leaves and red fall foliage add up to a winner in a shady garden area.

Plumbago’s gentian blue flowers, copper seed heads, deep green leaves and red fall foliage add up to a winner in a shady garden area.

Last month, I wrote about ground covers you could use for covering sunny areas in a rock meadow. This month, I’m focusing on ground covers for shady, rocky areas. Growing ground covers among rocks will not only add color, but will help suppress weeds.

Here are several shade-tolerant ground covers that will grow tall enough to cover river rock:

  • Plumbago (Ceratostigma plumbaginoides). The first time I saw a photo of this plant, I thought that the brilliant, gentian blue flowers couldn’t possibly be as gorgeous in real life as they appeared in the picture. But when I later spotted this ground cover in bloom, I realized its flowers really are that spectacular. When you add deep green leaves and copper-colored seed heads to the mix, the plant is downright startling. And if that’s not enough, the plant’s leaves turn bright red in the fall. Because it spreads readily when regularly supplied with medium water, it’s a good choice for covering a shady rock meadow. In Colorado, plumbago will grow eight to 12 inches high and two feet wide or more. One thing to keep in mind, though, is that plumbago is very slow to green up. So don’t assume that you’ve killed it if it doesn’t start popping up with your other plants in the spring.
  • Spotted dead nettle (Lamium maculatum). Years ago, a neighbor gave me some spotted dead nettle, which I planted in a moist, shady spot. Within days, slugs had decimated that plant. I haven’t grown it since. However, slugs are less likely to be a problem in a rock meadow, so I believe this plant would be worth a shot in these conditions. Dead nettle boasts lovely green leaves frosted with gray, and it grows 6 to 9 inches high by 2 to 3 feet wide. This groundcover likes medium moisture in well-drained areas. Although its flowers are relatively inconspicuous, dead nettle will produce clusters of tiny two-lipped white, pink or purple blooms in late spring or early summer. Popular varieties include Nancy, Wootton pink and orchid frost.
  • Creeping Oregon Grape Holly (Mahonia repens). Talk about a plant you can just throw in the ground and forget—creeping Oregon grape holly will just take off on its own and envelop an area with its evergreen foliage. Once it’s established, it’s extremely drought-tolerant. I like this plant because, in addition to being outrageously tough, it’s always doing something. In the spring, Oregon grape sends up intensely yellow flowers, followed by clusters of deep blue berries, which mature in late summer. Although the berries are quite sour, they can be used in jellies. Then in the fall, the foliage turns reddish and provides a show throughout the winter. An individual plant will grow 12 to 18” high and about 24” wide, but it spreads quickly because of underground runners. If you want to control erosion, this plant is a great bet. The only down side is that Oregon grape’s leathery, spiny-toothed leaves tend to catch and hold onto litter.
  • Sweet woodruff (Galium odoratum). This plant has the most adorable whorled leaves and fluffy, fragrant, white spring flowers. It grows about 6 to 12 inches high, and it spreads like crazy if it likes its environment. Although sweet woodruff prefers part to full shade and medium to wet conditions, I’ve grown it successfully in some dry, sunny spots. Pair this little darling with periwinkle (Vinca minor and Vinca major), which also grows 6 to 12 inches high and blooms at the same time as sweet woodruff. Seeing vinca’s purple blooms surrounded by woodruff’s fluffy white blossoms is a springtime delight.
  • Rozanne cranesbill (Geranium ‘Gerwat’ Rozanne). I mentioned Rozanne in last month’s post about ground covers for sunny areas. But this versatile plant will grow successfully in part shade, as well. Rozanne’s cousin, bloody cranesbill (Geranium sanguinium) will thrive in both part shade and full sun, too. Whereas Rozanne generates large purple blooms all summer long, bloody cranesbill produces fuchsia blooms in the spring.

11 Lively Lovelies Can Turn Sunny Sea of Rocks Into Show-Stopping Meadow

“Water, water everywhere,

And all the boards did shrink;

Water, water everywhere,

Nor any drop to drink.”

You’ve probably read this verse from The Rime of the Ancient Mariner by Samuel Taylor Coleridge. It’s an apt description of the river rock mulch in my yard.

This year, I spent weeks digging rock out of the soil in my back yard so I can begin planting next year. I still have more to go. On top of that, I spent about 10 days last September expelling tons of rock mulch and landscaping fabric from my front yard.

There’s also a sea of rocks along the west side of my house and all the way to the back property line. It’s ugly. Am I going to remove that tonnage, as well? Not a chance. I may develop a small area for a vegetable garden, but the rest of the rock will stay. Life is too short.

Ralph's Creeper ground cover rose, nestled here in pink soapwort blooms and deep-cut prairie winecup leaves, is a drought-tolerant repeat bloomer that explodes with color. Use it to keep dogs from pooping in your beds.

If you, too, find yourself drowning in a sea of rocks, what can you do?

You can create a meadow of spreading ground covers and other perennials. Just move some of the rock out of the way, cut a hole in the landscape fabric, amend the soil with a little compost, and install seeds or baby plants.

If your area has a western or southern exposure with lots of sun, you can use plants such as these 11 lively lovelies:

  • Prairie winecups (Callirhoe involucrata). This long-blooming ground cover, a Plant Select winner, sends out runners up to 30 inches long. Because it grows about five inches high, it’s tall enough to hide rocks. Plant this puppy, and it will reward you with stunning magenta blooms from early summer till frost. In the fall, prairie winecups will produce small wagon wheels of seeds. Spread the seeds around, and you’ll have lots of babies by the following spring.
  • Soapwort (Saponaria ocymoides). When this evergreen ground cover is happy, it spreads far and wide. I have one exceptionally happy pink soapwort in my front yard that has grown into a plate that measures 40 inches wide and four inches high. After blooming in the spring, soapwort produces hundreds of seeds, which you can pull off and scatter to produce baby plants. Or you can simply wait for soapwort to self-sow and produce babies on its own for transplanting. Soapwort comes in both pink and white. I’ve found that the pink variety is more robust than the white.

    To install plants in a rock reservoir, simply move some rock aside, cut a hole in the landscape fabric, work compost into the soil, and transplant a small plant, such as this rugged little candytuft. It's still trying to bloom in December. Candytuft loves sun, but will tolerate some shade.

  • Candytuft (Iberis sempervirens). This tough, evergreen beauty erupts with masses of tiny white flowers in early to mid spring. It will spread 12 to 18 inches. If you sheer it after it blooms in the spring, it may rebloom in the fall.
  • Rozanne cranesbill (Geranium ‘Gerwat’ Rozanne). Another long bloomer, Rozanne grows about 18 inches wide and 24 inches tall. This ground cover’s purple blooms are simply stunning. You may have to cut it back in late summer if it becomes leggy, but it will rebloom till frost.
  • Sedums. Some of our beloved sedums, such as autumn joy, have been reclassified as the genus Hylotelephium for ease of pronunciation. Autumn joy (Hylotelephium ‘Herbstfreude’ Autumn Joy) produces pink blooms and grows 18 to 24 inches high. Low-growing Angelina sedum (Sedum rupestre ‘Angelina’) is one of my favorites, with its lime green summer color and orange/red fall/winter color. At three to six inches high, it’s tall enough to cover river rock.
  • Orange carpet hummingbird (Zauscheria garrettii). If you like neon orange, you’ll love orange carpet hummingbird. The plant explodes with tubular flowers in July and keeps pumping out blooms till frost. It grows four to six inches tall and 15 to 18 inches wide. Hummingbirds went gaga over this ground cover in my yard last year.
  • Ground cover roses. Some are hardier and more drought-tolerant than others. I’ve found that seafoam, a gorgeous white ground cover rose that grows about 30” tall, tolerates all kinds of abuse. One disadvantage is that white roses tend to turn brown in intense sun. So you might get away with a white rose in southern exposure, but I don’t recommend one in a western exposure unless it gets occasional shade, especially in the afternoon. Ralph’s creeper, on the other hand, produces vibrant red blooms throughout the summer. No brownout problems with this guy. I planted one in my west-facing tree lawn in Denver and rarely watered it, yet it bloomed like a banshee. If you have an area with lots of foot traffic nearby, ground cover roses will keep dogs from pooping in your yard.
  • Irises. With their strong upright form, irises provide a welcome contrast when you surround them with low spreading ground covers. The same goes for snapdragons. I’ve seen irises grow in the most godawful conditions, so a rock bed isn’t likely to intimidate them.
  • Snapdragons. These colorful biennials already populate my future rock-based meadow, thanks to the efforts of the previous homeowner. I just let their seeds drop in the fall and wait for new plants to emerge.
  • Mojave sage (Salvia pachyphilla). One of my newest favorites, Mojave sage is sometimes described as having silvery green foliage. Maybe my soil is different, but the Mojave sage in my garden has wonderful silvery foliage that happens to be blue. Although the plant displays showy mauve brachts surrounding violet-blue flowers, I actually prefer the foliage to the flowers and regard my Mojave sages more as small shrubs than as perennials. They grow 18 to 24 inches high and 24 to 30 inches wide.
  • Color Guard yucca. For drama and architectural form, it’s hard to beat evergreen Color Guard yucca. With its variegated, yellow-and-green leaves and masses of creamy white flowers on stalks, this plant is a showpiece. In Colorado, the plant grows in a clump two to four feet tall and two to three feet wide. However, its spikes can shoot up five feet or so. In late fall, the leaves take on a rosy hue.

There are, of course, many other worthy perennials, and even shrubs, that you can use to disguise a rocky area. If you see one that you like at the nursery next spring, give it a try, as long as the plant tag indicates that it’s full-sun and drought-tolerant. Because light-colored rock reflects sunlight, it creates a great deal of heat for plants, and dries out the soil. You can, of course, irrigate your rock bed, but where’s the fun in that?

Next month, I’ll tell you about perennials that you can use in shady rock beds.

The Evergreens No One Talks About

In late November, evergreen color guard yucca is beginning to take on red tones. My tabby, Steve, normally takes no interest in this plant unless I'm photographing it.

In late November, evergreen color guard yucca is beginning to take on red tones. My tabby, Steve, normally takes no interest in this plant unless I’m photographing it.

Is there someone in your family that relatives don’t talk about? The crazy aunt, or the cousin with three drug convictions?

Well, it’s a similar situation with evergreens. Everyone talks about stately firs and majestic pines. But no one mentions the no-needle plants that, year in and year out, quietly add color to the winter landscape. Unlike weird relatives, these stalwart performers are good guys.

Take soapwort (Saponaria ocymoides), prostrate speedwell (Veronica prostrata) and woolly speedwell (Veronica pectinata), for example. These ground-hugging plants remain attractive all year round. Soapwort and prostrate speedwell display medium green foliage, whereas woolly speedwell turns slightly purplish in cold weather. Then when flowering bulbs peek out of the ground in early spring, these ground covers provide a carpet to showcase crocuses, snowdrops, daffodils and the elegant miniature Iris reticulata.

Robust soapwort retains its healthy green color throughout winter.

Taller, more woody evergreen ground covers include creeping Oregon grape holly (Mahonia repens)and kinnikinnick (Arctostaphylos uva-ursi). Oregon grape holly ground cover grows about a foot tall, and it will take over an area quickly, if you let it. Kinnikinnick is a cold-weather-loving plant that will reach about eight inches in height. This berry-producing native prefers northern and eastern exposures in Colorado.

Mojave sage's appealing foliage lends a soft blue tone to the winter landscape.

Mojave sage’s appealing foliage lends a soft blue tone to the winter landscape.

Mojave sage (Salvia pachyphylla) lends a subtle blue hue to the winter landscape. Its leaves may eventually turn yellow as winter progresses, but even then, this perennial subshrub provides winter interest with its gently upright form. Lavender, too, is a praiseworthy choice for providing blue tones in winter.

Other evergreen beauties are Manhattan euonymus (Euonymus kiautschovica ‘Manhattan’) for protected areas, manzanitas, yuccas (such as the variegated Yucca filamentosa ‘Color Guard’), and brooms, including my favorite dwarf broom, Genista lydia.

So if you want to create year-round color in your landscape, consider some of these cold-hardy choices.
