Genus

Asarum are evergreen or deciduous, rhizomatous perennials forming a mat of long-stalked, heart-shaped or kidney-shaped leaves, sometimes with attractive silver mottling, and curious flowers consisteng of a 3-lobed calyx, often in "earthy" colours. They are commonly referred to as wild gingers (they are not culinary gingers) but are so-called because their rhizomes have a similar spicy scent
