What zones can Black Deervetch grow in?
Black Deervetch is hardy in USDA Zone 10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Does Black Deervetch need full sun?
Black Deervetch does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
