This plant is known for its tough, woody stems and round, glossy leaves. It typically grows in temperate climates and can be found in forests, thickets, and along riverbanks. The plant has a dormancy period during the winter months.
Roundleaf Greenbrier requires moderate care. It prefers medium light conditions and should be kept in a location that receives around 6 hours of light daily. The plant thrives in moderate temperatures and humidity levels. Regular watering is necessary, but the soil should be allowed to dry out partially between waterings.
Soil
Smilax rotundifolia prefers loamy soil that is well-draining. The soil should be kept moderately moist but not waterlogged. A soil pH of around 6.5 is ideal for this plant.
