Very refreshing, Heuchera 'Lime Rickey' (Coral Bells) features gently ruffled and frilled, lime green leaves that retain their luminous colour throughout the growing season. In late spring to early summer, panicles of small, bell-shaped, pure white flowers bloom on slender stems rising up to 18 in. (45 cm), above the semi-evergreen foliage. A terrific choice for adding a touch of colour in the rock garden, perennial border, along paths or in containers.
