Abstract
Gliricidia sepium blooms in the lowlands of Guanacaste, Costa Rica from December to february and sets the pods from February to May. In the Central Valley, it bloom s with a two month delay, thus, blooming occurs simultaneously in both areas in February. Leaf fall begins in December and new leaf primordial develop in February. Germination is epigeal, phanerocotylar and begins between 48-96 hours after the beginning of the imbibition of the seed. The stem reaches a length of 25-30 cm after 4S days and secondary growth begins between 38-43 days of the initiation of germination.
