Family: Saxifragaceae
Common Name: Coral Bells

There are 55 species of mostly low-growing perennials in this genus from North America, mainly grown as groundcover. They are also well suited to growing in rockeries or at the front of garden beds. Many form rosettes of growth with foliage that is rather like that of the true geranium. Dainty, hell-like flowers are carried on tall stems high above the leaves. The flowers can be cut for the vase although they will last very much longer on the plant. All species flower in spring or summer.

Species

H. americana, zone 4, grows 40-80 cm (16-32 in) high and has coppery green foliage and brownish green flowers.

H. micrantha, zone 5, grows to 60 cm (24 in) and produces white flowers flushed with pink.

H. sanguinea, coral bells, zone 3, is most often grown. With crimson flowers, it grows to about 60 cm (24 in). This species has been widely hybridized and there are cultivars with white, pink and deep red flowers. Some of the cultivars have quite pretty, marbled foliage.

Cultivation

Grow in full sun to part shade in light soil enriched with organic matter. Partial shade is best in warm regions. They should be given ample water during dry spring or summer weather. Species can be grown from seed. The rosettes can be lifted and divided every three or four years to increase stock. Cultivars must be divided to maintain their character.

Climate

There are species suited to various cli­matic zones.
