Erica cinerea ‘Pink Ice’ – An RHS Award of Garden Merit winner with clear rose-pink bell-shaped flowers from summer right through to early autumn. These are nicely contrasted by the deep green needled foliage that takes on hints of bronze in winter. Bell Heathers require acidic soils (add peat moss) with good drainage. Grows 6 to 8″ high by 12 to 15″ wide. Hardy to zone 6.
Erica cinerea ‘Celebration’ – This Bell heather features intense bright chartreuse to lime green foliage with white flowers that are borne from July through to September. I use this as a foliar plant as the flowers are almost incidental, virtually lost in the blaze of the electric yellow canopy. Plant in groups of three to five for the best effect. Grows 8″ high by 16″ wide. Hardy to zone 6.
Erica cinerea ‘P.S. Patrick’ – Another RHS Award of Garden Merit winner with bright violet-purple blooms from summer through to early autumn. These contrast nicely against the deep green needled foliage. ‘P.S. Patrick’ makes a nice flowering groundcover and forms a dense mat when the shrubs are planted close enough together. Grows 6-12″ high by 18″ wide. Hardy to zone 6.
Erica cinerea ‘Alba’ (syn. Erica cinerea f. alba ‘Alba Minor’) – Pure white bell-shaped blooms are held from June to October over light green foliage. This RHS Award of Garden Merit winner, like all Bell Heathers, should be lightly sheared just after flowering in order to maintain a dense canopy. Prefers part to full sun exposures. Grows 6-12″ high by 2′ wide. Hardy to zone 6.
Erica cinerea ‘C.D. Eason’ – This cultivar of Bell Heather was discovered by C.D. Eason growing near Dorset England. It is an RHS Award of Garden Merit winner and bears magenta-pink bell-shaped flowers from June to September over mid green needled foliage. ‘C.D. Eason’ is also hardier than most Bell Heathers. Grows 9-12″ high by 24″ wide. Hardy to zone 5.
