I’m thinking of planting broom. Yes, one of those small, shrubs with the yellow pea-like flowers. Before you shudder and call me crazy, realize that invasive Scotch Broom (Cytisus scoparius, right) isn’t the only broom in cultivation, and the characteristics that led gardeners to import brooms in the first place are shared by many other species, some of which are hardy enough to survive drought, hot sun, and cold winters.
It’s January, but my brain is in July. I need to imagine warm breezes, green leaves, and most of all, bright flowers. And what is more reminiscent of a hot, summer day than a bright yellow sunflower? When we think of sunflowers, the image that comes to mind is a large brown disk surrounded by brilliant, sunny petals, kind of like this: Continue reading “Perennial Sunflowers”
When Russian Sage (Perovskia atriplicifolia) first appeared on the scene, I jumped right on the bandwagon, extolling its virtues and recommending it for Colorado gardens. I even planted it in my own yard. And yes, this hardy perennial lived up to my expectations. It was tough, drought-tolerant, and the deer and rabbits left it alone. On top of that, late summer brought a wealth of gorgeous lavender blossoms that covered the plant’s ferny, silvery-gray foliage. What’s not to like?
I’ll tell you. The plant is a thug.
Ask any 4-year-old what color leaves are, and they’ll confidently proclaim, “Green!” And green leaves are just fine, for the most part. We expect gardens to be basically green, from the verdant lawn to the tops of the trees (at least during the growing season). When it comes to plants, that glowing, chlorophyll-derived green implies life and health.
But one can have too much of a good thing. That’s why our landscaping includes plants with leaves that are a soft silver (that sounds much better than “gray”). No, I don’t want an entire yard full of them, but as accent plants, silvery leaves can make quite the impression.
I love to visit botanic gardens (look for my previous posts under the category Gardening: Gardens). In addition to enjoying the beauty of these places, they also provide ideas for my own landscape. Denver’s is one of the best, and many of the plants there will grow happily 2,000 feet higher. But many won’t. The Betty Ford Alpine Garden, in Vail, is another lovely spot, but that garden features plants that only thrive in the mountains, where they enjoy exceptionally well-drained gravelly soils and cooler days. Yes, there are several demonstration gardens here in Colorado Springs, and I’m well acquainted with what they have to offer. But perhaps I’m too well acquainted. I need inspiration that I can apply at home.
This summer, I found a botanic garden with growing conditions just like mine. In just five acres, the Yampa River Botanic Park, in Steamboat Springs, offers all the inspiration I could ask for. And since it’s situated at 6,800 feet, what grows there will grow for me, too.
Do you enjoy big flowers with bright, showy colors and carefree maintenance? It’s hard to beat annuals for season-long impact. Whenever I think of annuals, I immediately think of cosmos, one of the very best annuals for Colorado gardens.
There are currently thought to be 36 species in the genus Cosmos, but the two most often grown in our gardens are C. bipinnatus (left) and C. sulphureus. (There are two other Cosmos species in cultivation. One is a frost-tender, tuberous perennial known as Chocolate Cosmos, C. atrosanguineus. The other is Cosmos parviflorus, a wildflower of the western United States.)
Yuccas are as much a part of the Colorado landscape as red rocks and towering peaks. I admit, I didn’t like them at all when we arrived 25 years ago. Yuccas? Yuck! But in the intervening years, they’ve grown on me. I now acknowledge that yuccas have their place—as long as it isn’t in my yard.
I think my initial antipathy came from driving by a yard in a Colorado Springs neighborhood. The homeowners clearly didn’t want to deal with landscape maintenance; their front yard was mostly rocks. A scraggly Ponderosa sat to one side. The only other plants were a few yuccas stuck between some ugly boulders. It was probably intended to be a xeriscape. I thought it was a “zeroscape”!
