Best used in partial sun landscapes.
Beginning in mid spring, dramatic, narrow-spiked Ligularia lends the beauty of its large serated triangular or heart-shaped leaves to any moist partial-sun garden. Then in summer until first frost, it adds tall slender spikes of flowers. A noble plant with huge leathery leaves, deep green on top, ebony on the reverse side. Give this moisture lover room as it can be 4′ across and 5′ tall. Fragrant yellow, spike flowers in early summer, held above the leaves. A hummingbird favorite. They can form a magnificent display in a mixed border and can look imposing as waterside plants where the inflorescences are reflected into the water.
Best in a rich, moist soil. Very impressive planted in groups or as a background in the perennial border. Though it does as well in well-drained soil just so long as it is never entirely dries out, Ligularia is also a true bog plant and can have water up to the head of the root without harm.
Ligularias are at their best when grown in cool, moist locations in part shade. Protect from hot afternoon sun. Required constant moisture.
Planting Instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Ligularias should be grown in fertile, deep, moist soil in dappled shade but with some protection from strong winds that may damage the inflorescences.
Pests or Diseases: They are relatively untroubled by pests and diseases but like many herbaceous perennials the young, tender, emerging leaves can be damaged by slugs and snails in the spring.
