Salvia azurea

Naturalised over a wide area of the South-East USA, this is a hardy perennial in Southern England. It will grow up to 5 ft. tall, but must have support as the stems have a very floppy habit. Flowering usually commences at the begimning of September, and lasts for about 1 month. The plentiful, small flowers are a delightful shade of azure blue, the lower lip having a white blotch. A sheltered, sunny area is recommended for S. azurea. Propagation is usually from cuttings, though it does sometimes set seed. Dormant in winter, it will start resprouting in March or April.
