Cyclamen Species, Hardy Cyclamen, European Cyclamen, Sow Bread

I have to say these cyclamen are incredibly resilient. I've always had problems with C. persicum dying as soon as the temperature hits 21...Read More°C (70°F). However, these can take it far beyond that, never showing any signs of wilting due to temperature. They're amazing when it comes to watering as well - no matter if the soil is dry or wet, they never wilt (unlike C. persicum). They don't seem to care whether they're in pots indoors, in pots in the garden, or in the soil either. They all grow equally well.
The day temperature where I keep them is 18-20°C (64-68°F), and at night it's 10-15°C (50-59°F). As for the light, I keep them away from direct sunlight, just like any cyclamen. I water the ones in pots as soon as the soil appears dry, sometimes even more often (it's going to depend on the ventilation in the spot where you keep them; there's almost none where I keep them (on a window shelf, with curtains on)).
Outdoors, they benefit being under a deciduous tree, as they seem to like the leaves covering them and the soil being rich. I put some leaves in some of the pots as well, and these plants became more vigorous compared to others. It appears they like their roots / corms / bulbs receiving low to no light. This appears to stimulate them to grow new foliage and blooms as well. It's also interesting that the spots and patterns become more obvious when the temperature drops + the moisture is high.
I took mine from the forest in September, after blooming, and oddly enough the ones indoors are about to bloom (now it's November; their blooming time here is usually from mid-July to early September).

My plants were started from seed in 2004, and have survived and done well since then.

Two winters ago (2010-11) I bought about 150 Cyclamen purpurascens seeds, some with regular leaf patterns, and some with Christmas-tree p...Read Moreatterns and silver, from Jan Bravenboer. (I also ordered Cyclamen coum seeds at the same time.) I sowed them in several pots, and placed them outside for the winter, since I assumed they required winter cold in order to germinate. Since then I've heard that they only require darkness, so perhaps I'll try that next time. It would maybe allow them to bloom quicker after germination.

They germinated the following spring and summer. Over this past winter (2011-12) they stayed indoors under lights. This summer, two of them are in bloom and probably have tubers at least an inch wide. Others are a variety of sizes, and are not yet in bloom.

The flowers are fragrant, similar to the indoor type of cyclamen, but a little less soapy and intense. Most of the leaves have unremarkable patterns, but four look interesting, with a larger area of silver or extra distinction between green and silver areas.

Cyclamen purpurascens is grown by Betty Ann Addison of Gardens of Rice Creek (formerly Rice Creek Gardens), who has found it to be consistently hardy, unlike Cyclamen hederifolium and Cyclamen coum. She has several plants in various areas of her gardens.
