Modiola caroliniana (L.) G. Don
red-flowered mallow, Carolina mallow, Carolina bristle mallow, bristle mallow, creeping mallow, wheel mallow, ground ivy
Native to tropical America (to as far south as northern Argentina) and warm temperate North America
An annual herb or broad leafed, perennial (forb), rhizomatous, prostrate, up to 25cm in height and covered with stellate (star shaped) and/or simple hairs.
Gardens, lawns, waste places, amongst medium trees; occurring in aquatic areas; in sand, wet soil; occupying watercourses; growing on irrigated land, in disturbed natural vegetation.
Stems and Leaves:
The stems are prostrate, hairy and can root at the nodes. The leaves are ovate to broad-ovate alternate and are 3-4cm long and 2-3cm wide. They are reniform (kidney-shaped), round or triangular in shape with 3 to 7 toothed lobes.
Flowers and Fruit:
The solitary flowers have 5 petals and are borne on peduncles (stalks) in the leaf axils. They are predominantly orange-red or red. Five hairy green sepals are fused at the base. Fruit is a wheel-shaped schizocarp, 7-9 mm in diameter which splits at maturity into 16-22 two-seeded segments (each segment is called a mericarp).
The red flowered mallow is easily distinguished from other members of this family by the red to orange corolla (petals), the leaves with their toothed lobes and its habit as a prostrate creeping herb that roots at the nodes.
