Pinckneya is a genus of flowering plants belonging to the family Rubiaceae.

It is a small tree of the southern United States closely resembling the cinchona or Peruvian bark.

It has pretty, large white flowers, with longitudinal stripes of rose-color.

Pinckneya pubens is native to poorly drained acidic soils, as along swamp margins.

Good pest resistance and distinctive flower characteristics make this species of interest to gardeners, who should ensure that it receives occasional irrigation over a dry summer.
