I'm not sure of the cultivar name of this one, as it was growing in my daughter's garden when she moved in. A beautiful, low growing, tough and hardy perennial which forms clumps of green leaves with slightly jagged edges. From early summer multiple flower spikes appear, each one packed with small but stunning purplish-blue flowers. Repeat flowers well if dead-headed. Heat and drought tolerant. Full sun. 50cm x 30cm. 9cm pot.
