Life cycle: Low-growing annual or simple perennial.
Leaves: Cotyledons are rounded to oblong. Gray-green leaves are alternate, compound and cloverlike, with three heart-shaped leaflets that attach at the pointed ends. Long-stalked leaves have smooth surfaces, but they are fringed with hair along the margins.
Stems: Low-growing, prostrate to erect stems with minimal branching at the base, up to 20 inches tall. Plants spread by long, slender rhizomes.
Flowers and fruit: Yellow flowers with five petals are found in long-stalked clusters. Fruit are ridged, hairy, cylinder-shaped capsules with pointed tips that range from 0.5 to 1 inch in length. The capsules explosively eject small seeds with a sticky coating up to several feet away. Seeds are mostly brown, ridged, oval and flattened.
Reproduction: Seeds and rhizomes. |

| Similar weeds: Creeping woodsorrel (Oxalis corniculata L.) Differs by having a more prostrate growth, lack of rhizomes, presence of aggressive stolons and foliage often more purplish green. |
