The Vernales section of primulas, correctly called section Primula, includes our beloved primrose, cowslip and oxlip, which are usually, but not always, pale yellow. There are also some bright pink species from further afield - not to mention the polyanthus hybrids, with appallingly vivid colours, fortunately kept away from us in municipal plantings in the middles of roundabouts.

Primula vulgaris - vulgar? Certainly not. Or does the name mean common, in the sense of plentiful? Not nearly plentiful enough. No, it was merely the most familiar to Linnaeus, who would probably have given this name to Primula sikkimensis if he had been Chinese. Anyway, lots of pale yellow flowers with orange centres, apparently on separate stems, although if you explore deeply enough you will find that they are actually an umbel.
