Virgilia

Description

Virgilia is a genus of flowering plants in the family Fabaceae, commonly known as the keurboom or virgilia tree. The genus consists of two species, both native to southern Africa. These trees have a high ornamental value and are widely planted as street trees and in gardens. The genus name is derived from the Latin word “virgo,” meaning virgin, referring to the white flowers that resemble a bride’s veil.
