Liriodendron is a genus of two species (although many more have been described in the past). One is native to eastern North America (L. tulipifera), the other to eastern Asia (L. chinensis (Hemsl.) Sarg.). Both species are cultivated as ornamentals but the former is by far the commonest and it has been recorded as an escape in Belgium. Their hybrid (‘Liriodendron x chinamerica’; Mabberley 2008) might become significant in horticulture. It is interfertile and reproduces from seed.
