Cyclamen hederifolium is a gem for shady spots and woodland gardens. It blooms late in summer and into autumn, one of the very few plants that will flower in shade at this time of year. The flowers are pure white or exquisite pink. I notice that bees seem to favour the pinks but ignore the whites.  

 And it's tough; the driest of dry shade will not defeat it. Marbled ivy-like leaves appear after flowering. It seeds and spreads readily to the extent that the foliage makes for a useful groundcover on otherwise bare soil.
