Heliotrope is a genus of half-hardy perennials which are usually grown as annuals but may be grown as perennial in zones 9 and 10. It is grown both for the attractive clusters of small flowers, which can be, blue, purple, or white, and have a delicate vanilla-almond fragrance. The older varieties are more fragrant.

It is found naturally in forests or wet areas. Heliotrope can be grown outdoors in moist, well-drained soil in full sun or indoors in a well-lighted area with some protection from the afternoon sun. It may bloom in spring, summer, or fall, depending on the cultivar.
