Rodgersia A. Gray

Rodgersia is a genus with five species, all confined to eastern Asia and the Himalayas. Four species occur in China (Pan & Cullen 2001). All these are also grown as ornamentals, although in the horticultural trade pure species seem to be rare (Jäger & al. 2008).
Two closely similar species or cultivars of them have been recorded in Belgium, either as escapes from or relics of cultivation. They mostly reproduce vegetatively, seeds are rarely produced (Stace 2010).
Additional useful information on the genus is provided by Rodgersia - Sichtung at:

1 Leaflets entire at apex, sparsely glandular hairy on upper leaf surface === Rodgersia aesculifolia
Leaflets 3(–5)-lobed at apex, glabrous on upper leaf surface === R. podophylla
