Helianthemum nummularium ( Sun Rose )
A moderate growing, deep rooted, evergreen, mat forming, shrubby perennials, reaching a maximum size of 2 x 4 feet though rarely over 1 foot in height, that is a widespread native to Europe, east to the Caucasus. It is found on dry grasslands and sand dunes in the wild. The Sun Roses are highly useful for the front of landscape borders, walls, rock gardens and containers.
The lance-shaped to narrow oval leaves are up to 2 x 0.6 inches in size. The foliage is deep green to silvery-gray depending upon variety.
The flowers, up to 1.3 inches across, are borne in clusters up to 12.
The bloom season varies depending upon variety but may last from early summer to early autumn.
Hardy zones 4 to 8 ( some varieties even hardy to zone 2 with protection ) in full sun to partial shade on deep, well drained soil that is not too wet during winter ( prone to rot with excessive wetness ). Drought, lime and clay tolerant but does not like excessive heat and humidity and will likely not survive a Georgia summer. It is recommended to throw some evergreen boughs over the plants during winter in harsh climates to prevent the foliage from scorching. Lightly shear plants back by about 1/3 after the first flush of blooming is over, to encourage fresh growth and repeat bloom. Propagation is from division or cuttings.
