genus with about ten shrubs or small trees, originating in southern Africa; P. lamerei is native to Madagascar, it is a small tree, which in the wild reaches the 4-5 m of height; usually in container it keeps within the two metres; it has enlarged trunk, in bottle, of greyish colour, covered by several large thorns, usually paired.
Plants that exceed one metre tend to branch out, giving rise to a roundish foliage; at the apex of the branches they produce large oval leaves, slightly leathery, glossy, of a dark green colour. In summer, the specimens exceeding the 150 cm of height can produce showy apical inflorescences, formed by clusters of big white flowers, very showy, delicately perfumed, followed by big dark fruits. P.
lamerei is the species more easily found in the nurseries, even if, among the lovers of the caudiciform plants, are diffused also other species, such as, for instance, p. brevicaule, dwarf shrub, with ramifications which rise little from the ground; p. rosulatum, on the contrary, is a small caudiciform shrub, much ramified, which produces small yellow flowers.
Exposure and watering
Exposure: they are grown in a sunny place, or at least very bright, away from direct sunlight in the hottest hours of summer. They fear the cold, and generally the minimum temperature should never fall below 7°C.
Watering: from March to September water abundantly, but leaving the soil dry between one watering and the other. During the cold months let’s irrigate sporadically the specimens grown in a place with minimum temperatures above 15°C, if grown in cold greenhouses it is advisable to avoid watering.
- Pachypodium are succulent plants that are widespread in nature in southern Africa (only 5 species) and Madagascar (about twenty species); their name comes from the Greek, pachys means large, and it is a very common plant….
Pachypodium: Other tips
Soil: they prefer dry, very well drained soils; usually we use a mixture formed by a part of peat, a part of lapillus and a part of washed river sand.
Multiplication: by seed or by cutting, taken from the specimens which have ramified.
Parasites and diseases: they fear the cochineal, which often appears in the lower page of the foliage, in case of cultivation in a poorly ventilated place.
