About Bell Heather C.D. Eason

Erica cinerea 'C.D. Eason' · also called Bell Heather, C.D. Eason Bell Heather · flowering

A compact, mat-forming evergreen subshrub native to the heathlands and moorlands of western Europe, prized for its vivid magenta-pink, bell-shaped flowers produced in dense racemes from early summer to early autumn (June–September). It is strictly an acid-soil plant and will fail quickly on alkaline or waterlogged ground. The most important care rule is to clip back the spent flower stems immediately after blooming to maintain a tight, bushy habit and prevent the centre from dying out. Erica cinerea is not listed as toxic by ASPCA; it is classified as mildly-toxic as a precaution since the genus is not on the confirmed non-toxic list.
