Conoclinium (Eupatorium) coelestinum

Conoclinium coelestinum
Essentially a hardy perennial Ageratum with fuzzy powder blue flowers in late summer and autumn. Best grown in a moist (or even wet) rich soil in full sun. Needs a long warm season to flower well but worth it for the very late display. To 18ins. Spreading but not invasive.
2L pots ~ £6.00
