Clustering fishtail palm Seeds

The Clustering Fishtail Palm (Caryota mitis, family Arecaceae) grows several unbranched stems in a dense clump and has bipinnate leaves with leaflets shaped like a fish's tail. The fruit irritates the skin, so handle it with gloves.

Sowing

• Soak the seeds in water for 48 hours.
• Sow 2.5 cm (1 inch) deep and keep them in a humid place.
• Seedlings typically appear within 1–3 months.

Size, indoors and out

• Outdoors up to 9 m; indoors usually 3–6 m.
• Stems about 10 cm thick, forming dense clumps.
• Arching fronds up to 2.5 m long.
• Small pale purple flowers open in clusters from the top of the stem downward.

Climate and care

• Optimal growth at 18–27 °C; sensitive to frost; outdoors in USDA zones 9–11.
• Light: partial shade to full sun outdoors; bright, indirect light indoors.
• Soil: well-draining, fertile, rich in organic matter.
• Water: keep moist but not waterlogged; water less in cool months.

The species is native to Southeast Asia. Clumps make a screen in the garden or a large potted palm indoors.

Handle the fruit with care

The fleshy berries ripen from green to red or black and contain oxalic acid, which can irritate the skin. Wear gloves when you handle them and keep the fruit away from children and pets.
