Bransford, W.D. and Dolphia
Maianthemum dilatatum (Wood) A. Nels. & J.F. Macbr.
False lily of the valley, Canada Mayflower
USDA Symbol: madi
USDA Native Status: Native to U.S.
An erect stalk, 2-4 in. high, bears two broad, glossy-green, heart-shaped leaves and a terminal, spiky cluster of tiny, white flowers. Subsequent berries are red. Since each stalk comes from an extensive, horizontal, underground root system, a single plant can, in time, produce hundreds of above-ground triads – two leaves and a flower cluster. Grows in the low patches and has slender racemes of tiny white flowers held stiffly erect just above heart-shaped leaves.
The genus name, from the Greek maios (May) and anthemon (flower), refers to time of flowering. This plant, which spreads by underground roots, makes an attractive ground cover in woodland gardens.
