Ligularias are perennial flowers that blossom in yellow and light orange in summer on bold stems. Its name comes from the Latin word ligula, which means little tongue, referring to the tonguelike shape of the large petal on each of the ray flowers. The plump, large leaves in rosettes are either round or kidney-shaped and are sometimes toothed.
Ligularias do best in partial shade and good, humus-rich garden soil that is kept evenly moist. Since the roots form large clumps, plenty of space should be allowed between plants.
Propagation: By division in spring or from seed.
Uses: Ligularias are great in the back of shady beds, along borders, in bogs, or planted at the edge of water gardens. The plants prefer afternoon shade.

Ligularia 'Dark Beauty' is remarkable with its large, dark foliage, adding a tropical look to shady areas. The clear yellow-orange flowers bring color to the dark side of the garden.
