Distribution and description

Euphorbia tithymaloides is native to tropical and subtropical North America and Central America. It prefers soil that is sandy, well-drained, and nutrient-rich, particularly with higher concentrations of boron, copper, iron, manganese, molybdenum, and zinc.[11][12] It is relatively intolerant of high soil salinity levels, but exhibits saline tolerance if well fertilized.[12] The plant tends to be taller and have more biomass if it is well-watered.[12] The plant requires a sunny area to grow in.[11]

 

The shrub can grow to 1.8 to 2.4 metres (6 to 8 ft) in height and generally is about 45 to 60 cm (18 to 24 in) in width.[13] The leaf is a simple angiosperm leaf, arranged oppositely on the stem.[2][13] Each leaf is sessile (attaching directly to the plant), and about 35 to 75 mm (1.4 to 3 in) in length.[2][13] The leaves are glabrous (smooth) and acuminate in shape, with entire (smooth) edges.[2][13] The veins in the leaves are pinnate.[2][13]

 

The plant terminates in a dichotomous cyme, with a peduncle supporting each flower.[2][13] The floral leaves are bifid (split in two parts) and ovate, while the involucral bracts are bright red, irregularly acuminate in shape (e.g., like a slipper), and about 1.1 to 1.3 mm (0.043 to 0.051 in) in length with a long, thin tube.[2][13] The flower is void of scent.[14] The male pedicel is hairy, while the female is glabrous.[13] The seed pod is about 7.5 mm (0.30 in) long and 9 mm (0.35 in) wide, and ovoid in shape (with truncated ends).[13]

 

The plant generally flowers in mid-spring.[2]
