What sort of size are the seeds and did you see the plant they came off? Right now it would all be very much guesswork.

Well, whatever they are, the seedlings are unusual - there's only one cotyledon and usually, single cotyledons are not rounded, but long and narrow - rounded cotyledons usually come in pairs or more. Post again when true leaves appear

They look like the volunteer Cyclamen that I had sprout on the north side of my house one year, but fuzzier--not a cotyledon, but actually the first true leaf, like peas. They stayed with one leaf for several months, but had a chickpea-sized tuber when they went dormant in April. Blooming started the following January. The parents of mine were miniature forms of Cyclamen persicum.

Tugb. that was my thought too! That is why I was trying to find out the size of the seed and what the plant looked like...

Sorry, MG. Here's hoping that they remember--unlike a few times for me!
