The white form of Leonotis leonurus, appropriately called alba, is an attractive variation occurring in nature. Leon (lion) and otis (ear) of the generic name are repeated in the lion ear common name of this plant, an offence against both lions and these flowers! Maybe the hairy aspect of the corolla suggested a resemblance.

The white flowers remind that there are also albino lions: leonurus meaning lion-coloured is thus still fitting (www.plantzafrica.com).
