Erica carnea ‘Springwood White’ – Also known as Winter Heath, ‘Springwood White’ is an older variety with a slightly trailing habit. The snow-white urn-shaped blooms appear from late winter into early spring and are borne over bright green, needle-like foliage.

The clear pink flowers are generally borne from February to April and these are nicely contrasted by forest green foliage.

Erica x darleyensis ‘Jack Brummage’ (Erica carnea x E. erigena) – An unusual cultivar with attractive bright gold foliage that picks up some bronze-orange highlights in winter. The rose-pink flowers can appear from late January and last until early spring. This gold-needled shrub is a good choice where contrast is lacking. Grows 12″ tall by 24″ wide, and is hardy to zone 6.
Erica x darleyensis ‘Kramer’s Red’ (syn. ‘Kramer’s Rote’) (Erica carnea x Erica erigena) – This cross of E. carnea ‘Myretown Ruby’ and E. erigena ‘Brightness’ is by far the best selling of the winter heathers. ‘Kramer’s Red’ features long-lasting deep magenta blooms that are contrasted by rich dark green foliage.
