This architectural shrubby spurge is displaying domed cymes of inflorescence in the Scented Garden.
The spurge family, Euphorbiaceae, occurs throughout temperate, sub-tropical and tropical zones, and comprises some 2,000 species of annuals, biennials, shrubs, trees and succulents. Euphorbia mellifera is limited to just Madeira, and is a shrubby species which can grow to 2m in height. It has lance-shaped foliage and produces terminal cymes of cyathia, which resemble flowers, which are characteristic of the genus Euphorbia. These are honey-scented, hence the common name honey spurge. As with all members of the genus, E. mellifera produces a white resinous sap which can cause irritation.
