Description: Pachypodium succulentum is a slow-growing caudiciform succulent shrublet with a large half-submerged tuberous stem.
The plant can grow up to 1.5 and 2.5 meters of height.
This species is not as deciduous than most Pachypodiums, and will generally not lose all its leaves in winter.
Flowers: Crimson, pink, or (rarely) white, with a darker mid stripe which appears with the leaves.
Blooming seson: August to December.
Seeds: It produces numerous seeds, although specialized pollinators are required to produce a good seed set.
Culture: They seem to be particularly prone to rot if allowed to get too wet in winter, or if cultivated under less than ideal conditions and care. Water abundantly in summer and give extra well-drained soil to avoid waterlogged conditions. No water from November to March. The watering program will change, depending on temperatures and stage of growth, but it is best not to let this plant dry out completely for any length of time. It is sensitive to cold, and should be kept totally dry in winter, at or around 4°C. Protect from frost. It tends to lose its leaves and go dormant in winter. It likes full sun to light shade . It develops a great, succulent root system that you could raise up yearly and it would look better and better.
