The Banksian Rose - Rosa Banksia

Rosa Banksia was originally introduced from China in 1809. The typical species (Alba) bears small white, double, pleasantly-scented flowers in clusters in early summer. There is also a yellow variety of roses (Lutea), which are equally pretty. These roses are not quite hardy, hence will only succeed against a south wall and in fairly good soil ID a well-drained border.

They will do well also against the back wall of a sunny, cold greenhouse. A warm greenhouse is not suitable, as the heat would encourage too much free growth at the expense of flowering. Pruning should be done after flowering in June or July, cutting away gross shoots of the current year's growth that are not required to form future branches to fill up space, reserving the smaller twiggy shoots which alone will bear flowers next season.
