Appearance
Most Stellaria species are small, herbaceous plants that grow up to 30 cm tall. They have simple leaves that are arranged oppositely along the stem. The flowers are typically white or pink and have five petals that are deeply divided, giving them a star-like appearance. The fruits are capsules that split open when ripe to release numerous small seeds.
Care Guide
Stellaria plants are generally easy to care for and can tolerate a range of growing conditions. Here are some tips for keeping your Stellaria healthy:
- Water: Stellaria plants prefer moist soil, so make sure to water them regularly. Avoid overwatering, which can cause root rot.
- Fertilization: Stellaria plants don’t require much fertilizer, but you can give them a balanced, water-soluble fertilizer once a month during the growing season.
- Soil: Stellaria plants prefer well-draining, fertile soil with a slightly acidic pH (around 6.0-6.5).
- Sunlight: Stellaria plants prefer partial shade to full sun. In hot, sunny climates, they may benefit from some afternoon shade.
- Hardiness Zones: Stellaria plants are hardy in USDA zones 4-9.
Common Pests & Diseases
Stellaria plants are relatively pest and disease-free, but they can be susceptible to some common issues:
- Aphids: These small insects can suck the sap from Stellaria plants and cause stunted growth and yellowing leaves. Use insecticidal soap or neem oil to control them.
- Slugs and snails: These pests can eat holes in the leaves and damage the flowers. Use organic slug bait or handpick them off the plant.
- Root rot: Overwatering can cause the roots to rot and lead to wilting and yellowing leaves. Make sure to provide well-draining soil and avoid watering too frequently.
Habitat
Stellaria plants are found in a variety of habitats, including meadows, fields, woods, and wetlands. They prefer moist, cool environments and can tolerate some shade. Some species are also adapted to arctic and alpine environments.
