An excellent architectural plant that forms large spreading mounds and bears glandular flowers of pale bluish purple. A rather unusual plant with an ability to flower almost continuously from late summer to early winter. Reputedly growing to a height of 1.2m (4') or more and loving the shade this is a plant that must not be missed. Hardy down to -15. Lovely.
