Several cultivars are also cultivated for garden use,[6] including 'Grandiflora', whose flowers are purple-red and yellow.[4]

The plants are hardy, forming low-lying clumps up to 6 inches (15 cm) high[4] and 20 inches (51 cm) in diameter. They may be propagated from softwood cuttings taken in early in the growing season. Some varieties grow best in ericaceous conditions.[6]
