Perennial with tall wiry stems and tubular purple flowers in mid to late summer, which bob gracefully about in the breeze. Enjoys any reasonably well drained soil with lots of sunlight. Will gently seed itself around once established.
Open and transparent habit up to 1.5m. Mulch in winter and cut back old stems in spring.
IF IT HAS AN AMBER TRAFFIC LIGHT
Hardy in the Home Counties if sensibly sited (avoiding severe frost pockets, for example). Many Amber Labelled Plants are from cuttings from well-established plants that have survived many harsh winters in the South-East.

General Point about Plant Hardiness: The commonly held belief that it's better to 'plant small' is perfectly true with herbaceous plants, but not necessarily true with woody plants. They need some 'wood' on them to survive severe cold - so plants of marginal hardiness in very cold areas should really be planted LARGER, rather than smaller, wherever possible.
