This clumping plant offers edible tubers, which can be roasted or eaten raw.
Lovely vanilla-scented flowers will appear from late spring to summer and they’re ideal for attracting butterflies. The flowers can be white, pale pink, through to pale blue.
This perennial enjoys a full sun to part shade position in free draining soil and should grow around 50cm – 90cm high by 30cm wide.
It will become dormant in summer so mark it with a label so you don’t pull it out whilst weeding.
