Ligularia
A family of long lived perennials that seldom need dividing that enjoy moist, shady sites. Do not plant in dry shade under trees with competitive roots. Most Ligularias will grow on wet soil and tolerate flooding. Disease problems dont often occur, though they can be prone to slugs and snails.
The leaves will often wilt in hot sun even if the soil is moist, perking up during evening or nightfall, generally however they prefer a site without afternoon sun.
Propagation is from seed during spring. The seed can be planted into containers then later transplanted out to the garden.
Ligularia dentata ( Bigleaf Ligularia )
A perennial, forming a large clump up to 6.6 x 5 feet ( foliage clump along is 3 x 5 feet ), that is native to China and Japan.
The very attractive, toothed, heart shaped, leaves are red-purple in spring before turning deep green to grayish green. The leathery leaves are up to 24 x 20 inches in size and are borne on either green or reddish stems. The orange-yellow flowers, up to 4 inches across are borne on clusters up to 1 foot across, on tall, sturdy stalks during autumn.
Prefers sun to partial shade from zone 3 to 7 on moist to wet, deep, fertile soil with a deep organic mulch to keep the soil cool. Heat tolerant but may wilt during mid afternoon only to bounce back at night.
Reflected sun, especially against a south or west facing wall could cause severe scorching and stunting of growth.
