Jane, this article is a readable explanation of how ploidy works in plants… <…>  Bottom line is tetraploids and diploids generally don’t mate and in the rare occasion they do you get a sterile triploid.  It’s not uncommon for hybridizers to create triploid lilies, ’Tiger Babies’ is a triploid I know.

Apparently the latter is now known, at least by some botanists, as Cyclamen confusum. The note in our wiki describes it as a tetraploid. This would explain why my plants have very large, thick leaves that are more rounded than those typical of C. hederifolium. In the area where the C. confusum is growing, a number of self-sown seedlings have appeared, all of the same large size.

If they have a doubled chromosome number, however, does that mean they can't hybridize with the diploid typical C. hederifolium? Would it be useful to provide seed this summer to the BX/SX?
