These stately perennials from China and Japan form 3-ft.-wide clumps of large leaves topped by daisy-type flowers in yellow to orange. All need rich soil, plenty of moisture, and some shade; they do not tolerate low humidity or hot afternoon sun. Good around pools, along streambeds, in bog gardens. Control slugs and snails. Clumps can remain undisturbed for years; if more plants are needed, divide clumps in early spring.
L. dentata. Grown primarily for big, attractive leaves (to more than a foot across), roundish with a heart-shaped base. In mid-summer to early fall, sends up 3- to 5-ft. stems holding large, branching heads of orange- yellow, 4-in.-wide daisies. 'Othello' and 'Desdemona' have deep purple leafstalks, veins, and leaf undersides; upper surfaces of leaves are green. 'Midnight Lady' has dark, bronzy purple leaves.
L. 'Gregynog Gold'. Clump of 14-in.-wide, heart-shaped, tooth-edged leaves sends up stems to 6 ft. tall. In late summer and fall, stems bear conical clusters of 4-in. yellow flowers.
L. 'Osiris Caf Noir'. Grows 20 in. high and nearly as wide. Purple-black new growth progressively lightens through bronze to green. Leathery leaves have serrated margins. Yellow flowers appear on 20-in. stems in mid- to late summer.
L. przewalskii. LEOPARD PLANT. Deeply lobed and cut leaves grow to 1 ft. wide. Dark purplish blossom stalks rise to about 6 ft. and are loaded with dense, narrow spires of -in., yellow flowers in summer. 'Dragon's Breath' is more compact to 30 in. high and 24 in. wide.
L. stenocephala. Especially stunning flower spikes. Usually represented by its selection 'The Rocket', which forms a large clump of foot-wide, irregularly toothed leaves topped by tall (up to 5-ft.), narrow, dark-stemmed spires bearing many 1-in., yellow daisies in summer.
L. wilsoniana. GIANT GROUNDSEL. Bears kidney-shaped leaves that reach 20 in. wide. Stems grow to 6 ft. tall, carry spikes of inch-wide yellow daisies in summer.
