Also a kind of
heliotrope,
Heliotropium arborescens, with dense clusters of small
purple flowers, and wide somewhat furry
leaves. The flowers' intense, warm
aroma justifies the name. But beware, all parts are
poisonous.
It is a half-hardy annual suited for borders, as it forms a low bush. Prefers warmth, and in warmer climes may become perennial. It was very popular in Victorian times. It originates in the Andes of Peru and has the synonym H. peruvianum.
Note this is not the herb commonly known as heliotrope.
