About
A compact, evergreen, frost-tender succulent shrub on which the stem's growing point has mutated into a line or crest, so that the plant eventually forms a dome to 90cm (3ft) high and 60cm (2ft) wide of ridged, undulating, reddish-green growth that resembles the appearance of brain coral. The small flowers are rarely produced, but can appear in spring and are a pinkish, green-yellow. It is usually grafted onto the stem of another euphorbia species. Its slow growth, temperature requirements and ornamental value make it an useful subject for a sunny window indoors.
