Two Fleabanes out now: the yellow Common Fleabane (below providing food for a Common Blue) resembles a small sunflower, but with glaucous, ‘furry’ leaves. It grows in damp areas and ditches and is more scarce further North. It contains an insecticide and was used, fresh or dried and burned, to ward off the many fleas that thrived in herbs and rushes strewn on floors in past times, the Romans used it in wreathes. The less showy Blue Fleabane grows in drier areas, grasslands and dunes. It was used to treat tooth-ache. Conditions: Sunny day. Temperature: Max 20- Min 12C.
