One of the best patches of this is in a local cemetery where it is allowed to grow, flower and seed before the mower is used and Roundup isn’t ever used. In our dry gar­den it grows well through the dwarf Chinese Ceratostigma plumbaginoides and Genista lydia. Flowering during late spring its silky pale blue flowers with a peacock eye painted on each petal is one of the joys. Sun or light shade. 30cm x 10cm.
