Covered with abundant, showy rose-like flowers in shades of orange, pink, yellow, and white in late spring to early summer, Helianthemum nummularium (Rock Rose) is a charming low-growing subshrub with an evergreen foliage of gray-green, lance-shaped leaves. Each flower opens for only one day, but new buds keep opening – enabling a long-lasting display (up to 2 months).
