These plants are native to tropical and subtropical regions of the Americas and are characterized by their striking, fragrant flowers that have long, narrow petals resembling spider legs. They typically bloom in late spring to summer and thrive in well-drained soils. The genus includes several species, many of which are popular in ornamental gardening due to their unique appearance.
