Camassia leichtlinii ssp. suksdorfii has long linear leaves as you would expect from a member of the Agavaceae family. This is a stunning perennial that repays planting space in the border with a reliable show of multiple upright racemes, covered in blue flowers. Opening from the base of the spike, the long petals twist together as they senesce.
Enjoys an open situation with a moist root run, yet dislikes waterlogged soil. Native to western north America and generally hardy with us. Once planted leave to their own devices as they resent disturbance.
