Anadenanthera colubrina

Anadenanthera colubrina

Anadenanthera colubrina is a striking and botanically significant tropical tree from the Fabaceae family, native to the dry forests and savannas of South America, from Brazil to Argentina and Bolivia. First described by (Vell.) Brenan and published in Kew Bull. 10: 182 (1955), this intermediate-growing species is known for its impressive stature in nature, its finely divided bipinnate foliage, and its round, fluffy white flower heads — characteristic of the Fabaceae subfamily Mimosoideae. Historically significant across South America, it has been used for centuries in traditional and ceremonial contexts by indigenous cultures. A fast-growing and architecturally bold tree for tropical gardens and large container cultivation.

Care Guide

• Light: Full sun to partial shade; thrives with several hours of bright direct light daily — essential for vigorous growth
• Temperature: Intermediate to warm; ideal daytime temperatures 25–35°C (77–95°F), slightly cooler nights 20–25°C (68–77°F); tolerates seasonal dry periods once established
• Watering: Water regularly to keep the soil consistently moist during active growth; allow the top inch to dry slightly between waterings; established plants develop good drought tolerance
• Humidity: Moderate to high humidity preferred, 60–80%; adapts well to a range of tropical and subtropical conditions
• Substrate: Well-draining, fertile soil with good organic content; tolerates a range of soil types but performs best with good drainage

Anadenanthera colubrina is a fast-growing, historically rich, and visually impressive tropical tree that brings bold structure and delicate, fern-like foliage to any large tropical garden or collection. A rare and significant South American species from Ecuagenera, grown with care in Ecuador.
