"Oddities - Tomatillo, Physalis, Cucamelon & Achocha

I adore tomatillos and we eat them in huge quantities - salsas, curries, pickled, great in chutneys, and any recipe that calls for unripe tomatoes ...
I no longer have any seed but because they are so prolific and you need 2 plants for fertilisation I know that seedlings will start popping up both where they grew last year and some fruit fell, and in the compost heap!

Well, this is frustrating as not a single tomatillo seedling has appeared this year. Normally I'm over run with them. I wonder if they become weaker or even sterile over time? They have been breeding back to themselves after all.
