Question: What do Erica and Beschorneria have in common?
Related documents: [0]  [DOC] Erica is a genus of roughly 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance. The genus "Calluna" was formerly included in "Erica" – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. "Erica" is sometimes referred to as "winter (or spring) heather" to distinguish it from "Calluna" "summer (or autumn) heather". [END] 
[1]  [DOC] Beschorneria is a genus of succulent plants belonging to the family Asparagaceae, subfamily Agavoideae, native to semi-arid areas of Mexico and Central America. They are generally large evergreen perennials forming clumps of grey-green leaves, with tall flower-spikes to 1.5 m . Marginally hardy, they may require winter protection in areas subject to frost.
