Culture

Comments and Curiosities

Phenology: Flowering from May to July.

The fruits, which ripen in the spring, have rounded shape and yellowish-green color. Are much appreciated by the local fauna. (From the Portuguese)

Conservation: Being a kind of very restricted occurrence and due to habitat destruction, runs some risk of extinction. However, in the case of a very ornamental plant nurseries, collectors are the distributing and planting lawns in parks and large gardens in other regions, reducing the danger of its eventual disappearance.
