Rick, you make a very good point. I hope in the seedlings I raise from deliberately interbreeding the not-yellow-Yellow-Bunting-seedlings, that the yellow will express again in a fair proportion of them. We'd expect about a quarter of them to be yellow if classic Mendelian genetics were at play, I think? It will be fun to see.
Ursula, if I harvest enough pumilum seed this year, you're very welcome to some.
