Euphorbia alluaudii f. cristata - (WA Prohibited)

Euphorbia alluaudii f. cristata is a crested form of alluaudii, a succulent shrub species native to southern Madagascar, where it grows in dry, deciduous thickets and spiny forest on limestone or rocky substrates. This unusual forma develops fan-shaped, undulating growth along its stem tips, replacing the typical upright branching habit of the species. The crests are grey-green to bluish in colour and may flush reddish under stress or strong sun. Unlike many Euphorbias, it bears few spines, and its reduced leaves are short-lived. Cyathia are rarely produced in the crested form and may not appear consistently in cultivation.

Care Tips:

• Light – Requires bright indirect light or filtered sun; protect crests from intense midday heat
• Water – Water deeply but infrequently; allow soil to dry completely between waterings
• Humidity – Performs best in dry environments; ensure good airflow to reduce rot risk
• Media – Use a sharply draining cactus or succulent mix with added pumice or coarse sand
• Temperature – Maintain above 12°C; protect from frost and cold drafts
• Fertiliser – Apply diluted cactus fertiliser during the growing season
• Repotting – Handle gently during repotting due to the fragile nature of the crests

Additional Notes:

• Known to be toxic
