About

Adenophora khasiana is a herbaceous perennial that can reach heights of up to 1.2 meters. It features robust, fleshy roots and erect stems that support lanceolate, serrated green foliage. In late summer, clusters of three narrow, funnel-shaped flowers in a pale lavender blue appear, gently nodding as they bloom.

About the genus
