Picrasma excelsa, commonly known as Picrasma excelsa, is a large tree native to French Guiana and has been introduced to several Central and South American countries including Bolivia, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Haiti, Leeward Islands, Nicaragua, Puerto Rico, Venezuela, and Venezuelan Antilles. This tree thrives in full sun and prefers moist, light (sandy) or medium soil, making it adaptable but requiring well-drained conditions. Picrasma excelsa can grow up to 20 meters tall and is an evergreen species, contributing to its distinctive appearance in tropical landscapes. The inner bark of Picrasma excelsa is edible and has been traditionally used in South American herbal medicine for digestive issues and to support immune function. It can be prepared in various ways, often used raw or dried before consumption. The tree's bark is also known for its use in pest control, making it a practical addition to gardens and landscapes. While the inner bark is safe for consumption, it is important to note that Picrasma excelsa should be used with caution and under the guidance of a healthcare professional, as traditional uses do not necessarily equate to modern medical recommendations.

Transplant young saplings into larger pots or directly into the garden after hardening off.
Water regularly to keep soil moist but not waterlogged. Place in a sunny spot.
Provide full sun and regular watering, especially during dry spells. Prune lightly to maintain shape.
