How would you like a perennial that is hardy from USDA zones 3 through 9, tolerates browsing deer, drought, and smog, while attracting butterflies with its brilliant flowers? Moss phlox (Phlox subulata, also known as moss pinks and creeping phlox, does all that, and more. A very low growing groundcover that barely reaches six inches in height, moss phlox spreads to a diameter of two feet, making it ideal for the front of a border. The leaves resemble short, prickly pine needles, and are a gray-green in color. But it’s the flowers that cause me to run to the garden center for more.
It’s such a pretty plant, petite and delicate, only a few inches high and covered with quarter-inch flowers of the softest pink. It’s the kind of groundcover perfectly suited for small spaces, rock gardens, and fairy bowers. It can even be used as a lawn substitute, as it tolerates limited foot traffic. With so much to recommend it, I’ve often wondered why this hardy perennial isn’t more popular. Perhaps it just needs a better name. “Soapwort” fails in the marketing department!
Appearance
After months of dreary landscapes, Aubrieta’s vibrant purple flowers bring welcome color to the April garden. The diminutive blossoms have four petals arranged in a cross, with a clump of yellow stamens in the center. In early spring, they bloom enthusiastically, completely hiding the low growing mats of evergreen foliage. The plants only reach six to twelve inches tall but they can extend as far as two to three feet wide.
Angelina Stonecrop is a garden asset all year long. In summer, the low-growing succulent forms spreading mats of cheerful yellow-green, adorned with clusters of yellow star-shaped flowers. These blooms attract butterflies. But it is in winter that Angelina really shines, when those same fleshy leaves turn an incredible, brilliant orange, with subtle shades of red and yellow. The colors are so intense, the ground appears to be on fire. Such a show would be welcome at any time, but is especially appreciated when everything else is dead or dormant.
As summer’s flowers fade, plants that produce berries take center stage. Branches covered with bright red berries make cotoneasters especially attractive now, but they offer year-round interest. In spring, tiny but abundant white to pink flowers may be obscured by the shiny round green leaves. Foliage turns orange-red in fall. Finally, the berries persist into winter, or until the birds pick them clean.
The hardest part of growing cotoneaster is pronouncing it correctly (it’s “ko-TON-ee-AS-ter”). These shrubs thrive with little attention, handling poor soils, full sun to afternoon shade, and moderately low amounts of water. New shrubs should be coddled a bit until vigorous growth begins. Give plants room to spread, pruning only to remove oldest wood and enhance appearance. As with all members of the rose family, cotoneasters are occasionally susceptible to fire blight; some new varieties are tolerant of this disease. The many different species in cultivation vary in hardiness. Most will survive zone 4 or 5 winters, but check the label for the variety you are purchasing.
