Mandevilla is a woody-stemmed twining climber with funnel-shaped to tubular flowers each with five broad, spreading petals. It is an excellent choice for growing on a pergola, arch, or trellis.
There are about 120 species of Mandevilla native to Central and South America.
Mandevilla grows in full sun to light shade. In hot regions, grow Mandevilla where they get dappled shade during the hottest part of the day. They grow best in average to rich, well-drained soil.
In cold winter regions, grow Mandevilla in containers that can be brought indoors in winter. The indoor temperature for Mandevilla should be at least 65°F. Otherwise, treat them as annuals. Overwintered plants should be cut nearly to the ground in spring; they will produce new shoots and flowers in the same year.
Grow Mandevilla from seed started in spring or from cuttings taken in late spring or summer.
