Ligularia dentata (Bigleaf Ligularia) is a perennial ligularia plant for moist soil. Ligularia dentata is often used in borders and wetlands. You will find facts and information on growing and caring for ligularia dentata varieties.
Ligularia dentata plants grow in USDA Zones 3-8. It will reach heights of 3-5’ and will grow 3’ wide. It has a coarse texture and a medium growth rate. Bigleaf ligularia is a type of ligularia that is well suited as plants for wet areas that stay wet and overly moist, such as wetlands. It is important to choose the correct type of plants for this type of soil. You might also find Royal Fern growing in the same conditions.
Bigleaf ligularia prefers full sun, with light afternoon shade in warmer climates, and deep, fertile, moist soil with a pH of 5.5-7.0. The flowers are daisy-like blooms with a yellow-orange color with a brown center that appears from summer into early autumn. Place this plant in an informal area where the soil is reliably moist. Good companion plants include ‘Variagatus’ sweet flag and yellow flag iris.
Lingularia dentata Care
Plant 24-36” apart in spring or fall. Apply slow-release granular plant food at time of planting. Water deeply when the soil begins to dry. Apply 3” of vegetative mulch in summer and winter to help retain soil moisture. Deadhead spent blooms to encourage reblooming.
*Note: Ligularia often wilts in the aftenoon, even when the soil moisture is adequate so do not be alarmed at this.
Ligularia Propagation: If plants are not deadheaded, they self-seed in the landscape. To reproduce desirable cultivars, divide in spring or fall.
Pests and Diseases: The plants are relatively pest free when cultural requirements (sun, soil, planting depth, moisture) are met. Slugs and snails may become pests in some cases.
