Plant Profile

Neodypsis decaryi (Triangle Palm)

This palm is endemic to the Madagascar, and it thrives in poor, dry soils. Its usual heights is 3-5 m with a crown spread of 5-7 m, and it grows best in full sun but can tolerate partial shade. The tall, stiff feather-shape leaves can grow to 3 m long. Fronds grow from the top portion of the trunk in three distinct rows, creating the shape of a triangle as petioles stack on top of one another and giving the title for this palm as the “most unique appearance”. Flowers and fruits are non-decorative. Best is to use it as a specimen. Very adaptable to soil types but should be well drained. This palm is naturally resistant to pests but may require regular fertilization to prevent yellowing caused by potassium deficiencies.
