Hibiscus syriacus
A young woody seedling featuring characteristic alternate, lobed leaves with serrated margins and a central green stem growing in a small container.
- Light
- Full sun to partial shade, requiring at least 6 hours of direct sunlight daily for best growth.
- Water
- Water regularly when the topsoil dries out. Moderate drought tolerance once established, but young seedlings need consistent moisture. Avoid letting the soil remain waterlogged.
- Growth
- Perennial woody deciduous shrub or small tree. Mature specimens typically reach heights of 8 to 12 feet with a spread of 6 to 10 feet, featuring a moderate growth rate.
Care instructions
Provide bright, direct light for optimal growth. Water thoroughly when the top inch of soil feels dry, ensuring the pot drains freely to prevent waterlogging. Maintain in a well-draining potting medium and apply a balanced, water-soluble fertilizer during the active growing season.
