Helianthemum nummularium, sunrose, is a semi-woody perennial shrub that remains a garden favorite year after year. From the second week of May until the third week of June, this low-growing plant is covered with small flat blossoms.
Varieties with many different flower colors are available. Some favorites are Wisley Pink', a dainty pastel, Henfield Brilliant', a glowing, deep coppery orange, and Raspberry Ripple'. All three have silver or gray-green foliage. There are also dark-green-leaved double red and white varieties.
Once the blooms are gone, the mounds of leaves
remain all year long. The silver- and gray-green-leaved varieties, in particular, look
fresh and beautiful throughout the winter. They are lovely in combination with other
evergreen plants, such as the rosy winter color of yellow iceplant (Delosperma
nubinginum), the burgundy and pale reddish-green shades of Sedum spurium, and the
shiny dark-green and burgundy foliage of Rocky Mountain Penstemon (Penstemon strictus).
