Vernacular names

Leuenbergeria bleo, formerly Pereskia bleo,[1] (rose cactus, leaf cactus) is a leafy cactus, native to the shady, moist forests of Central America, that grows to a woody, prickly shrub about 2 m tall with large, orange flowers resembling rose blossoms.

Description

Leuenbergeria bleo grows as a shrub or small tree and reaches a height of 2 to 8 metres with trunks up to 15 centimetres in diameter. The olive-green to brownish grey branches are smooth. The leaves are arranged alternately on the branches and are distinctly stalked with petioles up to 3 centimetres long. The leaf blade is 6 to 20 centimetres long and 2 to 7 centimetres wide, elliptic to oblong or lanceolate in shape. The five nerved leaf blades have four to six, often fork-shaped, side lobes. The thorns are either parallel in bundles or spread widely out. Long thorns on the branches are up to five to ten millimetres long. Along the main shoots there are up to 40 spines per areole, each 2 centimetres long.

The flowers are arranged in terminal lateral inflorescences. The bare, bright red, scarlet, salmon pink and orange-red-pink flowers reach diameters of 4 to 6 centimeters.

The fruits are conical, truncated in the apex, ripening yellow. They are edible but sour tasting.
Taxonomy

The first description of the species, as Cactus bleo, was in 1828 by Karl Sigismund Kunth.[2]
Distribution and habitat

Leuenbergeria bleo is found by rivers and streams in Panama and Colombia as well as in secondary forest, from sea level to altitudes of 1300 metres.

The Red List of Threatened Species of the IUCN lists the species as "Least Concern (LC)" or not at risk.
