Heliotropium arborescens ‘Fragrant Delight’ (Purple heliotrope)

The wild version of this heliotrope comes from the Peruvian Andes. During the Victorian era in England, it became popular, and many cultivars have been developed. Thomas Jefferson was among those who planted it, but the wild plant is not found in North America.

Flowers: Deep purple flowers continue blooming through much of the growing season. Not everybody agrees on the flowers’ scent, variously compared to vanilla, cherry pie, or even grape popsicles, but everybody agrees that they smell great Flowers appear from June to October.
