Distribution
North American distribution, attributed to U. S. Department of Agriculture.
Chickweed makes its appearance in the winter and early spring of Texas lawns, often prefering to grow right up against the base of a house. Its sprouts were a common source of greens on early navy ships and helped prevent scurvy before the discovery of vitamin C. Their small amount of saponins help give dishes containing chickweed a creamy texture, especially when diced finely and simmered in pasta sauces. It's also tastes wonderful in pesto, salsas, and raw food/vegan “green drinks” as well as greatly increasing the nutritional value of these foods.
The hairy “Mouse-Eared Chickweed” Cerastium vulgatum must be cooked before eating to soften the hairs on the stems and leaves.
