Cyclamen x hildebrandii (africanum x hederifolium) - this is intermediate between it's two parents. I keep it in the greenhouse.
Many years ago I obtained seed labelled "Cyclamen africanum album". It seems other have it and at least three of us have come independently to the conflusion that is actually a white form of this hybrid.
It comes easily from seed and is a nice easy going plant.
That aside it's an easy going plant which is often scented and helps to welcome in the season's change by flowering Aug - Oct. Flowers usually before the leaves. It sets seed freely and the seed germinates well.
Above the third plant in is the darkest I've seen. The fourth and fifth is from Tilebarn nursery (now closed).
