Cassia grandis (pink shower).
Abstract C. grandis is an element of lowland and riparian, semideciduous forests, occurring naturally from Mexico to South America. The species is usually 10-15 m high, and is very ornamental, especially due to its pink flowers which appear when the tree is partially defoliate and cover the entire crown. It is used in landscape design and urban arborization in tropical America, although in some cases its use is restricted due to the size of its fruits, which can reach 40-60 cm long. The species is recommended for live fences and revegetation in gallery forests in periodically flooded areas, but it is also adapted to a more or less pronounced dry season. C. grandis can be planted under direct sunlight in mixed tree systems, in fertile soils. The species has agroforestry potential for dry zones, especially in Central America, and is recommended for arborization of perennial crops and pastures, the fruits are highly appreciated by the cattle. C. grandis requires periodical pruning, however this may cause early decay and rot. The wood is used in construction, especially for carpentry, joinery, flooring, posts, beams, also for rustic furniture, tool handles, small bridges and boats. It is considered good for charcoal and fuelwood, and inadequate for cellulose and paper. In Central America, especially in Costa Rica, the membrane which surrounds the seeds is used as a substitute for chocolate, and is also used in many countries due to its medicinal properties. Researches have shown that extracts from this plant exhibit activity against the most common dermatophytes.
