Euphorbia cylindrifolia (WA Prohibited)

Euphorbia cylindrifolia is a dwarf Madagascan succulent native to the dry, rocky limestone regions of southern Madagascar, particularly in the Androka district. This species forms a compact, dome-like cluster of slender, cylindrical stems that arise from a central caudex. The stems are jointed and grey-green, with sparse, scale-like leaves that may drop during prolonged dry periods. It is a slow-growing plant adapted to harsh, xeric conditions, typically found growing in open, sun-exposed areas.

Distinctive features:

• Compact growth from a thickened underground caudex
• Slender, jointed cylindrical stems with minimal leaf development
• Small cyathia with reddish to purplish glands
• Native to limestone-rich soils in Madagascar's arid south
• Stems often appear segmented due to growth nodes

Care Tips:

• Light: Requires full sun to light shade; thrives with several hours of direct light
• Water: Water deeply but infrequently; allow media to fully dry out before rewatering
• Humidity: Prefers dry conditions; avoid humid environments
• Media: Use a coarse, mineral-based mix with excellent drainage
• Temperature: Best kept between 20–30 °C; sensitive to frost and cold below 10 °C
• Fertiliser: Use a dilute, low-nitrogen fertiliser once or twice during active growth
• Repotting: Seldom needed; repot when caudex becomes cramped or outgrows its pot

Additional Notes:

• Known to be toxic
