A lovely shade of blue. There are very few blue indigenous flowers compared to the other colours. There is also a white form. They are fast growing, frost and drought hardy and will do well in full sun or semi shade. They attract the insect and nectar feeding birds as well as butterflies. It’s a great ground cover for a small garden, in pots or hanging baskets. Mass planted it’s stunning. The name is derived from the Latin felix=happy which probably refers to the cheerful flowers.
