Genus of about 50 species of which Daphne x burkwoodii is known to the author as being of particular interest as bonsai, though, there seems to be no reason why other Daphne species would not be equally suitable.
Daphne x burkwoodii hybrids are semi-evergreen shrubs with lance-shaped mid-green leaves to 4cm long. In late Spring, they bear clusters of up to 16 flowers 8mm across. Flower colour is dependent on which variety is used of which there are many.
