Velvetleaf. A. Upper part of flowering stem. B. Cluster of seedpods.

Stems & Roots: Stems 1-2m (3 - 6 1/2ft) tall and occasionally taller, much-branched in the upper part, finely soft-hairy.

Leaves: Leaves alternate (1 per node), broadly heart-shaped, large, 7-20cm (3-8in.) wide with a sharp-pointed apex, shallowly round-toothed, soft-hairy and very velvety to the touch.

Flowers & Fruit: Flowers single or in small clusters fom the leaf sxils, each with 5 large sepals and 5 yellow to yellow-orange petals, 1.3-2.5cm (1/2-1in.) wide when open; the filaments untied to form a central column as in the mallows; the fruit form each flower is a circular cluster of 12 to 15 seedpods about 1.3-2.5cm (1/2-1in.) long, at first green but turning dark brown to black at maturity, each individual pod opening with a vertical slit down its back and containing several purplish-brown, V-shaped seeds about 1mm (1/25in.) long. Flowers from late July until autumn.

Habitat: Velvetleaf occurs in southern Ontario where it is increasing in corn, soybeans and other annually tilled crops and in waste places.

Similar Species: It is distinguished by its erect habit of growth, large, alternate, valentine-shaped leaves which are very soft-velvety to the touch, its yellow to yellow-orange flowers, each with a central column of staments, its ring of several seedpods produced from each flower, and in late autumn bu the rather grotesque to blackish stem with many erect clusters of seedpods.
