I am a medium-sized, single-trunked palm tree, known for my exceptionally neat and formal appearance.

My most defining feature is the arrangement of my leaf bases. They grow in three distinct vertical rows, creating a three-sided, triangular trunk.

My fronds are long, feathery (pinnate), and arching, emerging from these three points to form a handsome, triangular crown.

I produce large, branched inflorescences of small, creamy-yellow flowers that emerge from below the leaves, followed by small, blackish-brown fruit.

I am a relatively fast-growing palm that provides a dramatic impact without overwhelming the space.

I am native to the humid, subtropical forests of Madagascar.

I have Moderate water needs. I prefer consistently moist, but never waterlogged, soil.

Water me regularly, allowing the top inch of soil to dry out between waterings. I am somewhat drought-tolerant once established but will look best with consistent moisture.

I enjoy high humidity.

I am a sun-worshipper! I thrive in Full Sun to partial shade.

I will develop the strongest trunk and most compact crown with at least 6 hours of direct sunlight daily.

I can tolerate some shade, but my growth may be less dense.

I am a palm for warm climates and am best suited to USDA zones 10-11. I can survive in a protected zone 9b.

I thrive in temperatures between 18°C and 29°C.

I am sensitive to frost and prolonged cold. Temperatures below -2°C can cause significant damage.

I am a perfect focal point for tropical, Mediterranean, or modern landscapes. I work beautifully in containers while young.

Plant me in rich, moist, well-draining soil. I am adaptable to various soil types as long as drainage is excellent.

My symmetrical form makes me ideal for lining driveways or pathways, or as a standout specimen.

Ensure I have enough space for my crown to spread, which can reach 10-15 feet wide.

I am a moderate feeder. Apply a continuous-release palm-specific fertilizer in the spring and summer.

Palm fertilizers contain essential micronutrients like manganese and magnesium, which prevent frizzle top and other deficiencies.

Fertilize 2-3 times during the growing season for best results.

Scientific Name: Dypsis decaryi

Common Names: Triangle Palm, Three-Sided Palm

Plant Family: Arecaceae

Plant Type: Evergreen palm tree

NON-TOXIC. According to the ASPCA, I am not known to be toxic to cats or dogs. My non-toxic nature and striking form make me a safe and stylish choice for pet-friendly gardens.

While all plants contribute to cleaner air, as a palm with a generous canopy of fronds, I am effective at absorbing carbon dioxide and releasing oxygen, helping to purify the air around me.

Provides an unmatched, bold architectural form and a strong focal point.

Creates a tropical ambiance with a clean, geometric structure.

Produces flowers and fruit that can attract birds and other wildlife.

Relatively fast-growing for a palm, offering a mature look sooner than many other species.

Frizzle Top (Manganese Deficiency) - Causes stunted, necrotic new growth. Treated with a palm-specific fertilizer.

Potassium Deficiency - Appears as translucent yellow or orange spots on the oldest fronds.

Ganoderma Butt Rot - A fungal disease that can affect many palms, causing conks (fungal structures) to form on the trunk.

Root Rot - Caused by overwatering or poorly draining soil.

Leaf Spot Fungi - Can occur, especially in humid conditions with poor air circulation.

I have a moderate lifespan for a palm. Under ideal conditions, I can live for several decades, gracing a landscape with my unique form for many years. I grow at a moderate pace, reaching a mature height of 20-25 feet over time, and will be a long-term, captivating feature in your garden.
