Ceratostigma sp. 'Blue Snow Flower' or Chinese Plumbago
This has to be my flower of the week.
I have forgotten what species this is and I have just one plant of it with only two branches hanging on for dear life which are producing these intensely dark blue flowers.
This Ceratostigma is dreaming of a better life in a cool temperate garden away from the coast where it can reach its full potential as a hardy small shrub in a sunny or part shade position. The Chinese name 'Lan Xue Hua' means 'Blue Snow Flower' .
