Disambiguation comment. The common name uses a 'z' in the name, Suzanne's Spurge, whereas the specific epithet uses an 's', viz. susannae. The problem is that a search on a misspelled species name, 'Euphorbia suzannae' lands on a completely different euphorbia species, Euphorbia suzannae-marnierae in the garden.org database. I have seen such a misspelling on a conservatory plant tag, and it may, in fact, be a fairly common mistake. Just be warned...

Spineless South African succulent from the Little Karoo near Ladismith. May grow nearly flat to the ground or form a mound of dozens of small knobby green heads. The tubercles are arranged in 10-16 rows and point downward. The stem usually branches heavily, and can be impressive in old age. Plants are male or female. Fall cyathia are small and greenish or brown, appearing in great numbers near the tip of stems. Male cyathia appear on short peduncles but female cyathia are sessile. Provide excellent drainage and strong light in cultivation. With proper care a long lived container plant. Named after Susanna Muir (note spelling "s" not "z").
