Pest Details

Dwarf Pearlwort
Dwarf Pearlwort


Native to Europe and widely distributed in the western United States.


An annual broadleaf plant that reproduces from seeds. Seeds germinate in early spring and plants mature in early summer, but can persist through the hot summers in cool, shaded locations.


Mature plants are mat-forming, but inconspicuous due to the small size of stems, leaves, and flowers. Mature plants may grow to 2 inches high, sometimes with stems growing prostrate along the soil and then curving upward. Stems are weak and threadlike. Leaves are very thin and only up to 1/5 inch long. They are flattened with the edges rolled inward, and are curved slightly toward the tip, which has a short bristle. Tiny flowers are borne on short, thin stalks. They may have 4 tiny white petals or no petals at all, and 4 larger green sepals.

Characteristicts Important to Control:

Annuals reproducing from seeds, and they prefer cool, moist habitats.
