Yes, here's a picture taken earlier this morning of Cyclamen graecum plants growing in our high plastic tunnel here in the UK, in a raised bed; these flowers too are going over now:

And outside in the open ground here are some Cyclamen hederifolium, also this morning (a bit misty), including a rather dark-flowered one. All these plants have grown from seed just scattered on the open ground:

In the same general area, but growing in much deeper shade under a Pinus pumila (a handsome Mexican pine with particularly long needles - the plants seed themselves very happily in the duff below the needles), more C. hederifolium. You may be able to pick out the much rounder Cyclamen coum leaves among the hederifolium. The coum actually flower better under this level of shade than the hederifolium, and stand their ground well against the much more vigorous hederifolium - which is never the case if you try to grow the two plants together in more open light:
