Description

Himalayan Indigo is a deciduous shrub in the bean family (Fabaceae) native to Afghanistan to Tibet and N. Myanmar. The Latin specific epithet heterantha means "with various or diverse flowers"

Grow Himalayan indigo in full sun in most any well-drained soil. In hot summer areas, it will appreciate some afternoon shade. The shrub can reach up to 7 feet tall and wide, with horizontal branches reaching 5 to 7 feet. It is drought-tolerant once established. In colder climates, it may die down to the ground and return in spring. It blooms on new growth so pruning can be done in late winter.

The hot pink to purple flowers appear from June to October in North Carolina in 3- to 5-inch clusters of pea-shaped flowers. The leaves are compound and are similar-looking to the mimosa tree. Dark purple seed pods follow the blooms.

Himalayan indigo has received the Award of Garden Merit from the Royal Horticultural Society.

Use this shrub in a cottage, cutting or pollinator garden. It will add color summer into fall and attract pollinators.
