This is probably the rarest flowering plant in the world as there are only 2 known examples. One can be found in a garden in New Zealand and the other is situated in a greenhouse in Britain. The plant was originally brought to Britain from China by John Middlemist (after whom the plant was named) in 1804. It has since been completely wiped out in China. The plant in Britain remained barren for years and only started bearing flowers recently. The flowers are, contrary to its name, bright pink in color and look almost rose like. It is believed to be highly possible that more examples of this species has survived in peoples gardens, unbeknown to them, as it was once sold directly to the public by John Middlemist.
