Bongardia is a monotypic genus - this means that there is just one species in the whole genus, Bongardia chrysogonum.
It is related to Gymnospermium and is one of a delightful group of tuberous plants within the Berberidaceae.
Early in spring it emerges with ornamental leaves each marked with a small red-purple spot at the base, and then, later the flower spike unfurls to reveal bright yellow flowers, the colour of 'lemon drops'.
Easy in almost any, well-drained soil in sun.
Order from Autumn list only.
