Very cute hummingbirds! Yes, I do tend to get which seeds I got from which trade mixed up--unless I take the time to go back and check. One of the passionflower seedlings got chewed off by a mouse but the other one is doing well.
In a packet from one of the trades, there was a seed included with some others that obviously wasn't the same as the others. (It was large, flat, and glossy.) I planted it anyway, just for fun, to see what it turns out to be. I don't recall whose seeds those were now, but once the seedling gets a little bigger, maybe I can post a photo to see if anybody recognizes it!
