Ligularia dentata 'Desdemona' features large, round to heart-shaped leaves that emerge in spring with a rich, deep green colour. The leaves have distinct serrated edges and a glossy texture. As the plant matures, the foliage can reach a height of up to 2 feet (60 cm) and a spread of 3 to 4 feet (90 to 120 cm). In mid to late summer, tall flower stalks rise above the foliage, bearing clusters of bright yellow, daisy-like flowers. The flowers contrast beautifully against the dark green leaves, adding a pop of colour to the garden.
Care Guide:
Light: Ligularia 'Desdemona' thrives in partial shade to full shade. It prefers dappled sunlight or a few hours of direct morning sun. Avoid planting it in full sun as this can scorch the leaves.
Soil: Provide a moist, well-draining soil that is rich in organic matter. Ligularia prefers consistently moist soil, so consider planting it near a water source or in a boggy area.
Watering: Regular and adequate watering is essential for Ligularia. Keep the soil consistently moist, but not waterlogged. Mulching around the plant can help retain moisture.
Fertilizer: Apply a balanced, slow-release fertilizer in spring to promote healthy growth and flowering. Follow the package instructions for the recommended dosage.
Pruning: Remove any dead or damaged leaves as needed throughout the growing season. After the first frost, you can cut back the plant to the ground.
Division: Every 3 to 4 years, consider dividing the plant in early spring to control its size and rejuvenate its growth. Dig up the clump, separate it into smaller sections, and replant them.
Pests and Diseases: Ligularia is generally resistant to pests and diseases. However, keep an eye out for slugs and snails, as they may damage the foliage. Using organic pest control methods or applying slug pellets can help manage these pests.
Winter Care: Ligularia is hardy in USDA hardiness zones 4 to 8. In colder regions, provide a layer of mulch around the base of the plant to protect it from harsh winter temperatures.
