Description

edit

Digitalis isabelliana is a broadleaf evergreen perennial shrub, growing up to 1.5 m (4 ft 11 in) in height, with a much-branched woody base. The leaves are broadly ovate, dark green, glabrous, and with a serrated margin. The flowers are russet, orange or terracotta in colour, with long, beak-shaped hoods, and grow in long spikes.[4][5]

Distribution and habitat

edit

Digitalis isabelliana grows primarily in the subtropical biome of the Canary Islands, where it is endemic to Gran Canaria, where it occurs on the moister northeast and centre of the island, favouring the undergrowth beneath stands of Canary Islands pine.[4][6] In the wild it favours damp and wooded areas.[7]

Conservation

edit

D. isabelliana is considered an endangered species due to diminishing habitat, with few large colonies.[4][2][8]
