Which flowering plant genus, Pelargonium or Sutherlandia, includes about 200 species of perennials, succulents, and shrubs, commonly known as geraniums?
Pelargonium Pelargonium is a genus of flowering plants which includes about 200 species of perennials, succulents, and shrubs, commonly known as geraniums (in the United States also storksbills). Confusingly, "Geranium" is the botanical name (and also common name) of a separate genus of related plants often called cranesbills. Both genera belong to the family Geraniaceae. Linnaeus originally included all the species in one genus, "Geranium", and they were later separated into two genera by Charles L’Héritier in 1789.
Erica 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".
