Euphorbia glauca is considered to be an endangered species as it is now found in relatively few localised coastal areas of New Zealand. It has a creeping rhizome from which red stems bearing narrow oblong blue-grey leaves become smaller and more crowded towards the top of the stem, where contrasting maroon coloured bracts surround the tiny flower. A distinctive and attractive foliage plant well worth growing in a sunny well drained site. It is moderately vigorous so needs room to spread or regular removal of the new shoots. Propagation best by division or cuttings.
