Plant Biography

The Euphorbias are one of the largest families of plants, present on all continents except Antarctica, with more than 2000 species and countless cultivars. Euphorbia characias originates in areas around the Mediterranean sea, where it prefers to grow in dry and rocky areas. It does not mind the salty terrains, making it a perfect plant for coastal gardens.

Euphorbia characias ‘Black Pearl’ has narrower flower spikes than many of the more familiar spurge cultivars but each cupped lime-green flower is dotted with a black centre giving a striking contrast.
