Asclepias tuberosa

Clump-forming herbaceous perennial with pea-like white and lilac flowers that appear from mid summer. The plant tolerates poor soil and partial shade, but will grow more vigorously in full sun.

This lovely cottage garden plant has spikes of purple-eyed white flowers that shoot up from glossy dark evergreen foliage. Flowers emerge from early summer and bloom right the way until early autumn. This plant is a biennial, so avoid cutting back spent flowers to allow them to self-seed.

This rare herbaceous plant has thin stems with wavy leaves that are topped by delicate cream and purple flowers shaped like little teacups. The flowers appear in spring and bloom all the way through to summer. This delightful plant is hardy and always grows back even after very cold winter weather.
