Cultivation details

Landscape Uses:Erosion control, Ground cover, Massing, Rock garden. An easily grown plant, succeeding in an open loamy soil[1]. The flowers vary in colour according to the type of soil they grow in, the best blue colour is formed when plants are in very acid soils[260]. One report says that this plant is probably not hardy outdoors in Britain[11] whilst another says that some provenances tolerate temperatures down to about -5°c[260] and another report says that the forms in cultivation are only fully hardy in southern Cornwall[1]. This same report goes on to say that those forms probably do not belong to D. febrifuga in the strict sense[1]. This plant is cultivated in Russia as an anti-malarial herb[240]. Special Features:Not North American native, Attractive flowers or blooms.

Plant Propagation

Seed - we have no information on this species but suggest sowing the seed in a greenhouse in spring and only just covering it. Do not allow the compost to dry out. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings. No details are given, we suggest trying in August with almost ripe wood in a frame.

In the coldest winters it looses its leaves but comes back in spring -3 is our average winter cold .occasionally -6 We take cuttings which root quite easily for insurance plants.It has a vivid blue flower that often gets confused with nearbt Hydrangeas

I have a shrub that I think may be a dichroa. Mine started flowering in September and is now at its peak. It matches the photos I've seen but there seems to be conflicting information about flowering times. If anyone could help with identification, I could send a photo. January 7th

forgot to sat that I live in Co Down, close to the sea. I had thought it was a hydrangea.
