CERATOSTIGMA WILLMOTTIANUM (Chinese Plumbago)

W China

Gillespie Park Fl - Ceratostigma Willmottianum (Blue Plumbago), planted in rock gdn behind centre

In late summer, this Bee-friendly shrub from China brings forth masses of small, intensely BLUE flowers. They bloom until first frosts, when the plant’s purple-margined leaves turn red. Ceratostigma Willmottianum likes warmth and a sheltered position out of the wind. Soil that is not enriched, but more impoverished, brings out the best in its cobalt-blue flowers. Carol Klein, writing in The Telegraph, reckoned that Hummingbird Hawkmoths are even better than late season Butterflies at extracting nectar from the flowers.

‘Ceratostigmas are found naturally on the rocky slopes of hot, dry valleys, often in rain shadows, and therefore demand good drainage and an open, sunny position in the garden. In cold areas where winters are long, ceratostigma is best grown in a sheltered position against a sunny, south-facing wall.’

The Chinese Plumbago is a native of the Himalayas. Here in North London, planted behind the Ecology Centre in Gillespie Park, it does well at the base of the rock garden slope.

My friend Anne has it in her west-facing raised bed in Wimbledon, where it flourishes in a sheltered position behind the birdbath and her ‘lawn’ of ‘Mind Your Own Business’. It fills the bed with a late summer haze of fabulous blue flowers.
