Rabbit Resistant or Not? The Poop on 10 Perennials

When I re-landscaped my front yard last September, I carefully researched lists of rabbit-resistant plants. I already knew that the plants I selected would, for the most part, be hardy and drought-resistant because I had grown several of them successfully in my old garden in Denver.

However, I didn’t have problems with rabbits in Denver. So I didn’t know which plants would really hold up against rabbit munching in my new Fort Collins landscape.

Here’s what I’ve discovered after planting the 10 perennials mentioned below.

Rabbit Food

Narbonne Blue Flax (Linum narbonense). Plant Select introduced this lovely selection in 2013, and I was eager to try it out. Narbonne reportedly has larger blooms, a fuller growth habit and a longer life that its better-known cousin, Colorado native blue flax (Linum lewisii). Unfortunately, rabbits sheared this plant to the ground within 24 hours of installation. So I may have to substitute either Linum lewisii or blue avena grass (Helictotrichon sempervirens) for a spot of blue in that part of the garden.

Orange Carpet Hummingbird (Zauschneria garrettii). It’s difficult to miss orange carpet hummingbird in a garden because of its neon orange, tubular blooms. This long-blooming, creeping Plant Select groundcover grows about six inches high and 18 inches wide. Surprisingly, the rabbits nibbled on this plant some, but didn’t eat it all the way to the ground, except on one occasion. So I think it stands a decent chance in the garden, especially because it spreads fairly easily.

Veronica (V. prostrata and V. pectinata). These two low-growing groundcovers have graced my gardens for the past 10 years or so. Because they’re evergreen, they provide an attractive organic mulch under late winter- and early spring-blooming bulbs. Then they produce their own show by carpeting the ground with small blue flowers in late spring or early summer. Unfortunately, the rabbits have taken a liking to some of the plants. I’m not giving up on veronicas yet, though, especially because they spread rapidly and may be able to outdistance the rabbits’ appetites.

Rabbit Resistant

Hidcote Lavender (Lavandula angustifolia ‘Hidcote’). I wouldn’t have a garden without lavender. It’s fragrant and evergreen, and on top of that, it produces delightful violet blue blooms. Hidcote grows about 16 inches tall and will spread as wide as two feet over time. After a few years, Hidcote will even begin producing babies that you can transplant around the garden. Munstead lavender is about the same size as Hidcote, but I prefer Hidcote because its leaves are softer-looking than Munstead’s are. ┬áThe rabbits haven’t touched my Hidcotes.

Mojave Sage (Salvia pachyphylla). A friend of mine raved about this plant so enthusiastically that I decided to try it. I love it already, even though it hasn’t bloomed for me yet. Its leaves are a soft blue color that complement the fuchsias, oranges and purples in my garden. This Plant Select winner, which grows about three feet high and wide, has a shrubby growth habit. Mojave is a showy bloomer that produces violet-blue flowers surrounded by mauve bracts. Although my Mojaves sit close to hedge cotoneasters that provide cover for rabbits, the critters haven’t bothered these sages.

Rozanne Cranesbill (Geranium ‘Rozanne’). Five of these loose-growing groundcover plants went under my autumn brilliance serviceberry. The geranium’s purple blooms brighten the garden from early summer to frost. Rozanne grows about one foot high and three feet wide. The rabbits left these plants alone.

Sonoran Sunset Hyssop (Agastache cana ‘Sinning’ Sonoran Sunset). This compact show-stopper produces fuchsia blooms on upright stems from late summer to through fall. One of my plants was still trying to produce blooms well after frost, and all five were still producing basal foliage in early winter. A Plant Select winner, Sonoran Sunset grows about 15 inches tall and 18 inches wide. The rabbits didn’t go near it.

Sunset Hyssop (Agastache rupestre ‘Sunset’). This Southwestern native is another show-stopper with its smoky orange flowers emerging from lavender calyxes. Sunset can grow up to 42 inches tall and 18 inches wide. The rabbits didn’t like it.

Soapwort (Saponaria ocymoides). This humble workhorse is one of my favorite groundcovers. It’s evergreen, and it produces white or pink flowers that attract pollinators. I placed it along a path in front of my house to serve as a mulch between pavers. In bloom, soapwort reaches a height of about four inches. The rest of the time, this stalwart hugs the ground. Soapwort looks like a plant that rabbits would savor, but they didn’t.

Color Guard Yucca (Yucca filamentosa ‘Color Guard’). As an experiment, I installed two of these bad boys near my front porch for drama. I’ll install a third as soon as one of my existing plants produces babies, which should be soon if these plants make it through the winter. During the growing season, the plant’s spiky yellow-and-green leaves provide excitement on their own. But when Color Guard sends up stems that are three to four feet tall and produces panicles of stunning white flowers, you really begin to appreciate its architectural grandeur. Color Guard is evergreen, but in Colorado, it’s a raggedy evergreen that makes you wish the plant would just dormant altogether. The rabbits have wanted nothing to do with Color Guard.

That’s the news so far on my new perennials and their relationships with rabbits.

In another experiment, I also installed three blue panda corydalis (Corydalis flexuosa ‘Blue Panda’) bulbs for their lacy leaves and early spring blooms. Rabbits have nibbled on them some, but it doesn’t look as though blue pandas are among their favorites.

Happy New Year. May your gardening efforts be wildly successful in 2016.
