This lovely popular dwarf succulent looks a bit little an itty-bitty cycad, except for its simple lancelote leaves. Very different and interesting.
Origin and Habitat: South Africa, widespread in the Eastern Cape Province and KwaZulu-Natal (from Grahamstown to Queenstown and in the Kentani District near Black Rock cove in the eastern region).
Habitat: It grows in tropical subarid grassland, open thicket and Savanna usually in shallow soils with a thin cover of grass. It is a widespread and relatively common species that is being harvested in large volumes for medicinal use in the western part of its range. There are concerns that the volumes harvested may be unsustainable.

Description: Euphorbia bupleurifoliaSN|17510]]SN|17510]] is a low-growing, spineless, plant with a short caudiciform trunk that looks like a small pine cone topped with a crown of green leaves. The whole plant abounds with milky juice.
Stem: It has a brown, spherical barrel-shaped or columnar caudex usually unbranched or occasionally few branched, that look like a pine-cone or a woody trunk. The stem which does not photosynthesise is a reserve for water, and usually does not grow much higher than around 20 cm and 7,5 cm thick. The trunk has a geometrically-neat tubercled surface, the tubercles (tuberculiform corky scars occasioned by falling away of the old leaves) are prominent dark reddish-brown up to 3 mm hight and crowded in many spiral series imbilicated in the centre giving a reticulate appearance to the surface.
Leaves: Deciduous borne in wet season and falling in the dry season, lanceolate, erecto-patent, willow -like, narrow or large, in dens tufts on the stems apex, 7-15 cm long by about 2 cm, not succulent, light green, making it look like a palm tree or a pineapple.
Flowers: The cyathia are solitary and quite small (about 5-7 mm in diameter), yellowish-green becoming reddish, cupped by 2 ovate bracts 1 x 2 cm wide. Nectar gland oblong, 2-lipped, margin entire or finely crenulate. They develop at the crown of the plant. The peduncles is 1-5 cm long and fall away after drying.
Blooming season: Spring.
Fruit: Subsessile about 9 mm in diameter and obtusely lobed.
Seed: Ovoid up to 4 mm long, smooth.

(Euphorbia bupleurifolia) Photo by: © Plantemania Tithymalus bupleurifolius (Euphorbia bupleurifolia) Photo by: Valentino Vallicelli Cultivation and Propagation: This is a small, slow-growing choice Euphorbia, and although not one of the easiest to grow, it should not be too difficult for the careful collector. It is suitable as a container plant (but it can grow in the ground in areas with a mild climate).
Soil: It grows well in a very draining mineral potting substrate.
Moisture: It does not like its compost drying out for very long periods when the weather is hot. It needs constant moisture during the Summer, but it doesn't like winter water, as it rots easily.
Hardiness: It needs to be kept warm, not less than 10 C in the winter (but when dormant and dry they are relatively cold tolerant).
Sun Exposure: Light shade.
Warning: The latex of the Euphorbia bupleurifoliaSN|17510]]SN|17510]] is highly poisonous, but has been used as an application to help cancerous sores, cracked skin on the feet and various other skin disorders. However, the latex can be very dangerous, depending on the dose given.
Propagation: Usually by seeds.
