Anadenanthera colubrina is a South American tree (5 to 20 m) in the pea family, related to yopo, with mimosa-like leaves that fold at night and a very thorny trunk. It is grown for timber, shade and ornament in seasonally dry climates rather than as a common houseplant.

About
Anadenanthera colubrina (also known as vilca, huilco, huilca, wilco, willka, curupay, curupau, cebil, or angico) is a South American tree closely related to yopo, or Anadenanthera peregrina. It grows to 5–20 m (16–66 ft) tall and the trunk is very thorny. The leaves are mimosa-like, up to 30 cm (12 in) in length and they fold up at night. In Argentina, A. colubrina produces flowers from September to December and bean pods from September to July. In Brazil A. colubrina has been given "high priority" conservation status.
How to grow it
A. colubrina grows at altitudes of about 315–2,200 m (1,033–7,218 ft) with roughly 25–60 cm (9.8–23.6 in) per year of precipitation and a mean temperature of 21 °C (70 °F). It tends to grow on rocky hillsides in well-drained soil, often in the vicinity of rivers. It grows quickly at 1–1.5 m (3 ft 3 in – 4 ft 11 in) per year in good conditions. The growing areas are often "savannah to dry rainforest." Flowering can begin in as soon as two years after germination.
