This is a small genus of choice, herbaceous plants thought of as belonging to the Berberidaceae or the Podophyllaceaea, depending on your views.
They form a lovely group of species, characterised by having just one or two large leaves, which are attractively marked in most species. The flowers are borne underneath, but do bear examination as they are fascinating in structure, colour and appearance. An added bonus is that most species will bear large red fruits in September.
They will grow happily in a well drained soil, into which lots of humus has been worked. A transient abundance of water, in spring, as they start growth, is helрful, but not essential. Light shade and humid air are equally beneficial and more necessary. They cannot however be considered difficult.
