Plant Biography

Dypsis decaryi originates in the Madagascan rainforest, however only a handful of them are left in the wild. The triangle palm is endangered in the wild, under threat from habitat destruction, flash fires and, historically, seed collection.

Commercially this pressure is now off as, where climate allows, it is becoming commonly cultivated, valued for its unique appearance and adaptability.

Care & Size Guidance

Care & Size Guidance

Dypsis decaryi prefer sharp drainage, so use a cactus and succulent potting mix but water regularly, without allowing the plant to stand in water. A well-drained soil is essential, allowing the top layer of compost to dry in between waterings.

It does not transplant well, so even if pot bound, it can stay for many years in the same pot. Keep in a well-lit area, preferably with direct sun in the morning. It can adapt easily to grow in a heated conservatory.

Feed regularly between April-September with a palm fertiliser.
