Yes Carol, I actually received the Heptacodium seeds at the end of January last l year. They were packed in a small amount of moist vermiculate. I put them in a larger bag with some more moist seed compost. I had them in and out of the fridge every 3 - 4 months. Then 3 seeds germinated in the fridge in November and December and I planted these small plants in a pot and distributed the rest from the bag on top of the pot with the small plants. I kept the pot in a half open plastic bag. 2 of the plants died so I thought: That is it
In the middle of January at least 10 more seeds germinated in the pot on the windowsill. They are still very small and I just hope that they will survive the winter.
