What it's good for, and what it isn't

Coral bells are grown mainly for their low mound of lobed leaves, which stays decorative almost all year: cultivars come in deep purple to near black, lime green, amber and peach, silver-veined or plain green, with thin stems of tiny white, pink or red bells above in summer. They do best in part shade in humus-rich, moist but well-drained soil: dark-leaved forms take more sun, while pale ones (lime, yellow, peach) scorch in strong sun, so match the spot to the leaf colour. They are not long-lived: the crown turns woody and lifts out of the soil, so divide and replant deeper every 3 to 4 years.

Watch out for

Vine weevil grubs in the soil eat the roots, so the plant suddenly wilts and lifts off the ground in your hand: this is most common in pots and tubs. Leaves scorch in strong sun and hot, dry weather, and crowns rot in heavy, wet soil, so plants are short-lived in such sites. Frost heaves the crowns out of the soil in winter: firm them back in spring or mulch with compost. Heuchera rust, powdery mildew and leaf spot also occur.
