I did the pollen crosses last summer and collected the seeds in October of 2010. Most of the seeds were started in November. They vary in how long they take to germinate; I germinate all of them in plastic baggies and then transplant them into pots, watering them every 7-10 days, or as they dry out. I give them 12-14 hours of light per day.
I usually transplant things in the fall, but had considered hardening them off and planting out in May. My deck will be pretty full if I take all of these out and leave them all summer there. There won't be any room for us! We'll see. It will be a year or two before I see any flowers on those shown up top ;)
