Abutilon theophrastii
Mallow family (Mallow family)

Description: This is an annual plant about 2-7' tall that branches occasionally. The stems are terete (circular in cross-section), and pubescent. The alternate leaves are up to 8" long and across (excluding the petioles). They are cordate or orbicular-cordate, slightly dentate along their margins, and more or less pubescent. The primary veins of the leaves are arranged palmately. The petioles are up to 4" long and pubescent as well. The foliage of the entire plant is mostly light green, although the upper surfaces of the leaves are dull green. 

From the axils of the upper leaves, there occasionally develops a single flower about " across. It consists of 5 petals that are orange-yellow or yellow, 5 sepals that are pubescent and light green, and numerous stamens with golden yellow anthers that surround the pistil in a loose cluster. The flowering stalk of each flower is about 1" long, which is much shorter than the petioles of the leaves. The blooming period usually occurs from late summer to early fall, and lasts about 1-2 months. The flowers are sparingly produced and short-lived. Each flower is replaced by a fruit about " across. It is initially light green, but rather quickly turns brown or black with maturity. This fruit consists of a ring of about 10-15 flattened seedpods. Each seedpod has a stout beak and contains about 5-15 seeds. Each seed is greyish brown, somewhat flattened, and either reniform (kidney-shaped) or cordate (heart-shaped). The root system consists of a stout white taproot. This plant spreads by reseeding itself.

Cultivation: Velvetleaf is typically found in full sun, mesic conditions, and a fertile soil consisting of loam or clay-loam. The fertility of the soil, particularly the level of nitrogen, has a strong influence on the size of the plant. The seeds can remain viable in the soil for at least 20 years, if not considerably longer.

Range & Habitat: This is a common plant that occurs in most counties of Illinois (see Distribution Map). Habitats include cropland (particularly corn and soybean fields), abandoned fields, vacant lots, construction sites, and waste areas. Velvetleaf typically occurs where the soil has been recently disturbed and the long dormant seeds are brought close to the soil surface. The seeds germinate during warm weather after the spring tilling of fields, and the new generation of plants develops and matures very quickly during the heat of summer, prior to the fall harvest. As a result, Velvetleaf is a major weed of cropland in Illinois. It was introduced into the United States from India as a possible source of bast.

Faunal Associations: The nectar and pollen of the flowers attract various kinds of bees, including bumblebees, leaf-cutting bees (Megachile spp.), miner bees (Melissodes spp.), and Halictid bees. Occasionally, small butterflies and skippers visit the flowers for nectar, while Syrphid flies feed on the abundant pollen. Two insects feed destructively on VelvetLeaf. The caterpillars of Pyrgus communis (Checkered Skipper) make folded-leaf nests from which they feed, while a scentless plant bug, Niesthrea louisianica, feeds on the floral buds, flowers, and seeds.

Photographic Location: A vacant lot in Urbana, Illinois. There is a small black bee visiting the flower in one of the photographs.

Comments: Velvetleaf is a rather tall and lanky plant with large leaves that is easy to identify in the field because there is really nothing else that resembles it. There are other weedy members of the Mallow family that have been introduced from abroad, but they are much smaller plants. Velvetleaf is about as tall as the native Hibiscus spp. (Rose Mallows), but the latter are perennials with darker foliage and much larger flowers. The seeds of Velvetleaf are reportedly edible. In an outdoor emergency, the soft leaves can be used as a substitute for toilet paper.
