About

Asclepias curassavica is a vertical, evergreen sub-shrub characterized by its elongated leaves and terminal clusters of orange-red blooms measuring around 2 cm in diameter, which appear during the summer and fall. These flowers may give way to upright, oval-shaped fruit that can reach lengths of 6 to 8 cm.
