Clammy Chickweed is the kind of plant that rewards close looking. The sticky, glandular hairs coating its leaves and stems give it a silvery-gray cast and the faintly gummy texture that earns it its common name. It appears in lawns, fields, and roadsides from late winter into spring, forming loose, erect clusters rarely more than six inches tall, its tiny white flowers opening in brief clusters before the heat of summer ends the whole performance.

As annuals go, it is both tenacious and temporary. Seeds carry it across a wide range of soils, from dry sandy edges to compacted roadside verges, wherever the ground is open and the competition thin. Understanding its life cycle is the most useful thing a gardener can know about it: the plant germinates in cool weather, flowers, sets seed, and dies as days lengthen and warm. Managing it early in the season, before seed sets, is nearly always sufficient.
