Aegopodium Native to Europe and western Asia. It is a genus of flowering plants of the carrot family Apiaceae, represented by about seven species, all are perennial herbs. Flowers are compounded, umbels appearing in spring-summer. Fruit consists of two-winged or ribbed nuts that separate on ripening.

The most well-known member is the Aegopodium podagraria, the ground elder also known as snow-on-the-mountain, Bishop's weed, goutweed, native to Europe and Asia. It is variegated green and white that sometimes reverts to solid green within a patch. Small, white, five-petal flowers are held about three feet high, above the leaves, in flat topped clusters. Underground are long white branching rhizomes that vaguely resemble quackgrass. Regarded as an ecological threat, goutweed is aggressive, invasive and forms dense patches reducing species diversity in the ground layer. On the other hand, because of this, it is often used as a low maintenance ground cover.

Cultivation Frost hardy but drought tender, preferring moist well-drained soil in an open sunny position. Propagate from seed or rhizome.
