Appearance
Virginia buttonweed has small, oval-shaped leaves that are arranged oppositely on the stem. The leaves are dark green and have a glossy appearance. The plant produces small, white flowers that are about a quarter of an inch in diameter. The flowers have four petals and are arranged in clusters at the end of the stems. Virginia buttonweed has a shallow root system and spreads by stolons, which are above-ground runners that produce new plants.
Care Guide
Virginia buttonweed prefers moist, well-drained soil and partial to full sunlight. It can tolerate a wide range of soil types, but does not do well in standing water. The plant should be watered regularly, but care should be taken not to overwater, as this can lead to root rot. Fertilization is not necessary, but a balanced, slow-release fertilizer can be applied in the spring if desired. Virginia buttonweed is hardy in USDA hardiness zones 8-11.
Common Pests & Diseases
Virginia buttonweed is relatively disease-free and pest-resistant. However, it can be susceptible to powdery mildew in humid conditions. To prevent powdery mildew, avoid overhead watering and provide good air circulation around the plant. Virginia buttonweed may also be attractive to aphids and spider mites. These pests can be controlled with insecticidal soap or neem oil.
Habitat
Virginia buttonweed is commonly found in wetlands and along the edges of ponds, lakes, and streams. It can also be found in disturbed areas such as roadsides, pastures, and lawns. The plant can tolerate both full sun and partial shade and is well-suited to hot, humid climates.
