Flowers that Beat the Heat

Heliotrope is grown as an annual in Zones 2 to 9 and as a perennial in Zones 10 to 11. It bears wonderful clusters of purple or white flowers, which are intensely fragrant with a deep, grapey smell. Leaves are glossy and attractive with slight ribbing. The plant will grow a foot or two high as an annual, or up to 4 feet tall as a perennial, depending on the variety.
