Randy, great to hear you included Copan in your grow-out but curious where you obtained your seed? I too wanted to raise Copan this season and Don sent me a packet of seeds in one of those yellow GRIN packets. I was quite happy to get the seeds and that they came from GRIN. I've got a couple of these plants growing but it took some extra care to get that far along.
First, there were only about 24 seeds in the packet and almost 1/2 were immature looking (hard to tell if I got the count correct because of the all the other debris in the packet). Anyway, the good seed would barely germinate (got 6 to show a white tip over a 6 to 10 day period). Only 3 of those developed true leaves. One of those didn't make it to transplant. I got the last two in the dirt and they are growing like little runts compared to the Turkish plants they are next to. Then, about 2 weeks ago one of the two plants that was 12" tall decided to bolt into bloom. I decided to bag it anyway. The other plant is still growing with no sign of a bud yet. It is about 16" and looks healthy, just a bit small. Now, back to the plant that I bagged, it has sent out 2 suckers that have grown to about the height of the bag. Looks a bit strange to see suckers that have grown about as tall as the parent. I'm letting the suckers develop. When I bagged this little runt I pinched off 3 of the mud leaves and hung them to dry. Couple days ago I took a tiny, tiny snippet of leaf from one of them and added to it my pipe tobacco and can attest to the fact that lots of nicotine is present in this plant.
