I only scanned this thread.... but I tried them on a heat mat, still nothing.
Maybe i'll quickly WS some.
Last year, I was at a Flea Market with friends and he bought one... had no idea what it was at the time, so I looked it up for them [they are Sr's with no PC]
I also told him, at the end of the season, he can over winter it in his house... I never knew what they did with it until about a week ago. I was talking to his wife and she said it is stunning and full of blooms. I think he has the green thumb, because she commented he wont let her touch it.
I cant wait to see it again this summer.
He has the Yellow one... the seeds i have are for "mixed". I got them in a seed swap.
now i'll finish this thread... then maybe i'll get some seeds sown today.... COLD gloomy day here, but warm temps are around the corner again.
