Rock Rose Mutabile Mix Helianthemum Nummularium is a semi-evergreen shrubby perennial native to Europe and Asia. Rock Rose Mix seeds have to be just slightly pressed into the soil and not covered, because the seeds need light to germinate. Other common names of Helianthemum Nummularium are Sun Rose, Mutabile Mix Sunrose, and Rockrose. Rock Rose Mutabile Mix grows low to the ground spreading rapidly and blooming profusely with numerous, five-petaled, brightly colored white, pink, rose, red and yellow flowers on a top of gray-green foliage with fine, woody stems and small, fuzzy, leaves that resist water loss. Sun Rose blooms from late spring to midsummer attracting bees and butterflies.
Rock Rose Common Mutabile Mix makes a lovely rock garden plant and ground cover for sunny locations, and Mutabile Mix is great for container, wall and bordering plantings. Helianthemum Nummularium seeds are easy to germinate, and the established Common Sun Rose grows best in dry, alkaline, rocky or sandy, well-drained soil in full sun tolerating drought.
