Astrocaryum vulgare aka Tucum Palm

Astrocaryum vulgare is an evergreen palm in the Arecaceae family. Its common names include tucuma, awarra palm, and tucum palm. It comes from northern South America and central Brazil. Its range includes French Guiana, Suriname, and northern Brazilian states. It grows in rainforest, disturbed ground, and savannah. Most sites lie on land that does not flood each year. People gather its fruit from wild plants and grow it locally.

This palm forms small clumps of upright, unbranched stems. Garden size reports range from 26–49 feet (8–15 metres) tall. PFAF gives a spread of 26 feet (8 metres). Broader accounts record stems reaching 66 feet (20 metres). Growth is moderate. Black spines cover the stems and reach 0.72 feet (0.22 metres) long. Each stem carries a crown of eight to sixteen stiff, upright leaves. These feather-like leaves reach 20 feet (6 metres), including the leaf stalk.

The round to egg-shaped fruit turns orange to orange-red. Each fruit has fleshy pulp around one large seed. The raw pulp tastes mildly sweet, with an apricot-like flavour. People use it in juice and the French Guianan dish bouillon d’awara. The pulp supplies provitamin A. Harvested fruit has a short storage life once ripe. Sources also list the seed, sap, and apical bud as edible parts. Fruit oil has uses in soap and fuel production.

Grow this palm in a warm, sheltered site with moist, well-drained soil. Young seedlings need some shade, while larger plants suit full sun. It accepts sandy, loamy, and clay soils. It prefers a soil pH of 5–7 but tolerates 4–8. Roots do not cope well with dry conditions. Wind exposure is also unsuitable. PFAF lists USDA zones 10–12. Temperatures at or below 36°F (2°C) can kill it. Its preferred daytime range is 68–82°F (20–28°C).

Its clumped form and large leaves give it a strong landscape presence. The long stem spines are a clear handling hazard. Leaves provide fibre for rope, hammocks, bags, and cloth. Leaflets also serve in basket making. Local traditions use roots, oil, and fruit as medicines. These reports do not establish safe or effective treatments. Sources report no known toxic hazards, but do not provide specific pet-safety evidence. Seeds lose viability in storage, and their hard endocarp slows germination. Fresh seed is best sown with some shade.
