'Tiger Babies' is one I try every year. I have it from s few different sources and one group in particular seems to get good seed. Since Tiger Babies it said to be a strain, I have focused on this group. I also have the same experience on the seedlings, often weak and lost early on. I will also add.. slow growing. But I do have one growing from a cross with Bruno. We'll see. Good luck Della.
I'm also a pod presser. The chaff pods, though looking full, seem to be softer with some give to them.
