A self-sown primorose, Primula vulgaris, at the edge of the stream. The plant managed to sow itself into a mass of Darmera peltata rhizomes with a finesse and a sense of composition that would outclass even the best gardener. The position could not be better. Leaving self-seeders to 'help the garden along' is a wise policy and often results in plants seeding themselves into nooks and crannies into which it would be impossible to plant them. Or, perhaps more to the point, the idea of planting them in that position would never occur.
