That looks like an excellent list. Not sure how you can stop at 42. I have 60 varieties, either rooting, rooted or in large gallon pots or ground, and several more promised and on my wish list. With my UC Davis order, I may make it to 100 varieties, or just under that number. Every single variety I own has certain attributes that made me desire to enjoy it's flavor. I have many varieties that were sent as bonuses, which forced me to learn about those, and I'm pleased with every single variety I have.
Good luck keeping that list at 42!
