The candelabra primulas (the Proliferae section) are wonderful plants, originating from China and the Himalaya, for woodland or damp, even extremely wet, places. They make clumps of strong leaves, deciduous in some species and persisting through the winter in others, and then send up their tall stems. At intervals up the stems there are whorls of ten or so flowers, each ring opening in succession, perhaps one every five or six days, . As there can be up to six, even seven, whorls, that gives an exceptional flowering period. So there can be a mass of colour – and that colour can be brilliant orange or yellow, red, pink, white, even dark maroon.

Primula poissonii has whorls of extremely bright, rich pink flowers with yellow eyes. It is from a site at quite low altitude, just 2600 m, where it was growing in water completely saturated with lime, where the pH must have been 8.4.
