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”
Last week’s garden post was devoted to All America Selections, a nation-wide program that highlights new cultivars most likely to succeed in your garden, no matter which part of the country you live in. Surprisingly, it seems to work for Colorado. But there’s an even better “seal of approval” for Colorado gardeners to look for, at least when it comes to shrubs and perennials: PlantSelect®.
It’s only November, but when it comes to gardening in a cold weather climate, it may as well be winter. From the first sudden freeze, now months ago, the leaves have been brown. For those of us who have gardened in more mild conditions, we crave green, especially evergreen shrubs, but the choices are severely limited. There are the ubiquitous junipers and other dwarf conifers. Yuccas. Firethorn (Pyracantha). Perhaps some Oregon Grape Holly (Mahonia) if you have a sheltered spot so the leaves can avoid desiccation. Even my supposedly evergreen Cotoneaster is brown. But there’s one often-overlooked shrub that stays green all winter—even if it doesn’t exactly have noticeable leaves.
What were those vibrant pink flowers? They were definitely show-stoppers, especially as they were spilling out of planters crammed full of flowers in other shades of pink plus various yellows—creamy white Cockscombs (Celosia cristata), pale pink, ruffled Cosmos and darker pink Globe Amaranth (Gomphrena), butterscotch-yellow Lantana, Petunias in either a lush purplish-pink or a pale cream with yellow throats, and finally, bright lemon Flowering Maple (Abutilon). Whoever had designed the display, situated along the walkway in front of the greenhouses at Denver Botanic Gardens, clearly had a good eye for shapes and colors. Continue reading “Pretty Purslane?”
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.
