Stellaria pubera aka Star Chickweed

Stellaria pubera has the common name star chickweed. It belongs to the carnation family. This wildflower lives for more than one year. It comes from the eastern and east-central United States. It grows in woods, on rocky slopes, and beside sandstone ravines. Plants reach 0.5–1 foot (0.15–0.3 metres) tall. They spread 0.5–1.7 feet (0.15–0.51 metres) wide. Their low, spreading growth can form small groups of plants.

The weak stems have few branches and bear fine hairs. They range from pale green to green with purple tones. A taproot supports a network of thin roots. The green leaves are simple, not split into leaflets. They grow in pairs across from each other along stems. Some are oval; others are narrow and shaped like lances. The leaf edges lack teeth. Fine hairs cover the leaf surface. Most leaves join the stem with no stalk. Lower leaves may have short stalks. Later shoots do not bear flowers.

White, star-like flowers form clusters called cymes at stem tips. Some also grow where upper leaves meet the stem. Each flower has five petals. Deep splits divide them into narrow lobes. These splits make each flower look like it has ten petals. Ten stamens stand around the centre. They bear reddish-brown anthers, the parts that hold pollen. Sources place bloom time between March and June. Spring is the main bloom season. Flowers open in the morning but stay shut in dull weather. Egg-shaped seed pods, called capsules, follow from May to July. Each opens through six curved teeth around its rim. Each holds many small seeds with fine bumps on their surface.

Grow star chickweed in dappled light or part shade. It prefers more shade as the season moves past spring. Keep soil moist, but let excess water drain away. Acid soil rich in organic matter suits it well. A layer of rotting leaves also meets its woodland needs. In these conditions, it accepts clay, loam, and sandy soil. NC State lists USDA zones 4–11 and calls care easy. Plants grow fast, and richer soil makes them fuller.

Star chickweed covers the ground and draws bees. Bees pollinate the flowers. Caterpillars feed on the leaves. NC State reports no known disease problems. Leaves, young shoots, and seeds have food uses. But leaves contain saponins, so large servings are unwise. Cooking them well breaks down these compounds. PFAF advises against use while pregnant or breastfeeding.
