I fared well with C. purpurascens and hederifolium in Kansas. Both grew for more than 5 years. My original purpurascens from Ellen Hornig is now with me here in E TN. It must be over a decade old now. Our soils were different. In Kansas I had heavy clay vs. your Missouri loess. I always failed with coum. It would flower, but died shortly thereafter. Even caucasicum. Hederifolium persisted, but never seeded around. Here in E TN I can keep coum alive, but it only likes being planted on the surface. Adzharicum (=caucasicum?) seems to prefer being buried and grows better than typical coum. I have two typical coum that rest on the soil with a few roots holding them in place. They seem happy. Herederifolium is a weed, purpurascens is flowering now in force. Graecum does not last long. Persicum ex Golan Heights died. Elegans died. Pseudibericum perished over last winters mild conditions (why?!). Creticum flowers every year strangely enough. Libanoticum died. Confusum flowers, but has yet to set seed. Cilicium grows well enough, but is so small I don't find it worth the space.

Most cyclamen prefer light open shade with even an hour or two of sun, preferably in the morning. We have found that good soil preparation with lots of compost makes a HUGE difference in the performance of cyclamen in the garden. If you just throw them into poorly prepared ground, your results will not be good. Cyclamen need to be dry in the summer during dormancy. We found that this can be best accomplished by putting them near a large tree or shrub. Cyclamen actually don't mind summer irrigation as long as the soil dries quickly. I would encourage folks not to give up after a few failures.
