(Spurge)

This remarkable tree-sized, branching succulent is a coveted landscape plant in arid, frost free regions. Originating from Saudi Arabia and Yemen, it is common in southern Africa where it was introduced long ago by traders, but is now listed as a threatened species in its native habitat.

Forming a branched, candelabra-like outline, this thorny succulent superficially resembles a cactus, but is not actually related to them. Its needle-like barbs are borne on vertical ridges that divide its...

(Candelilla)

This fine textured succulent thrives in the world’s driest places, offering a unique component to desert landscape design. While the majority of Euphorbia species are native to southern Africa, this is a rare example of a New World plant. Its range is limited, from Texas south into Mexico, preferring rises and low foothill locations where soils are poor and drainage is extreme. The plant is composed of slender pale green stems narrower in diameter than a pencil, growing knee high. These...

(Spurge)

This rare species of succulent is among the most beautiful of its clan due to compact growth and mounding habit. It is native to rocky, dry inland mountain ranges of South Africa where it is often found among outcrops. This slow growing plant produces a single trunk that branches into many growing tips, producing a cushion-effect in gardens. The geometrical stems are angular, bearing dark red to black spines that give a higher aesthetic value, particularly for larger uniform specimens.

(Slender Candelabra)

One of the more beautiful large Euphorbia, slender candelabra has an exceptional upright form and produces many stems of bright green. In fact, mature wild specimens can produce as many as 50 branched stems. A native of southern Africa, specifically the Auas Mountains of Namibia and along the Orange River of Botswana, it is frost-tender but very tough and drought tolerant.

The upright, bright yellow-green stems of slender candelabra have distinct vertical ribs lined with pairs of dark...

(Mediterranean Spurge)

Massive, bright green flower heads top the leafy, hairy stems of Mediterranean spurge in springtime. This upright, shrubby perennial is native to the western Mediterranean, where it thrives in upland, open, seaside sites with dry, sharply drained soil.

Dense whorls of narrow, grayish green leaves encircle the purplish, hairy stems of Mediterranean spurge, adding to its bold, architectural looks. The foliage remains evergreen to semi-evergreen through winter. Airy, rounded flower clusters are...

(Glacier Blue Spurge, Mediterranean Spurge, Variegated Spurge)

Glacier Blue variegated spurge offers blue-gray foliage edged in creamy white, lending extra visual appeal to its bold, architectural form.
