Upright habit and profuse rich blue flowers. Reputed to be quite hardy. Discovered as a self-sown seedling in the famous Sissinghurt garden.
Thrives in very well drained, poor soils, preferably neutral to alkaline, in full sun. Dislikes excessive winter wet. Best to cut back regularly to retain a bushy shape and prevent the plant becoming leggy. Can be damaged by severe winters in cold areas.
Traditionally used as a culinary herb, but also makes an attractive ornamental shrub for hot, dry positions such as a Mediterranean style garden. Can be used as an informal hedge in mild areas.
