Brian,
Thank you for updating. I think I am personally most interested in kumquats myself of all citrus. My sunquat, you helped me with on my other post, is finally arriving from harris citrus this thursday. I now have 4 different varieties; Hong Kong, a very young grafted Nagami (I was impatient to let my rootstock grow), soon to be sunquat, and this spring on backorder is a meiwa (I may cancel and wait on harris updating their shop for one). Meiwa is the only one I have tried so far, and WOW, I LOVE the sweet flavor and crunch it has. Like crisp salad only, you know, has flavor.
I'm interested in mandarins, but I am container only and I want things that flower profusely. Do mandarinquats carry this from kumquats? I also am having a hard time finding any online to purchase. Would you ever in the spring (or whenever you prune) consider selling any budwood of your varieties to Wisconsin? (unless in quarantine of course) I have very recently finally taught myself how to graft.
Also, the red lime seems very interesting! That is a kumquat variety? You eat the entire fruit whole, minus seeds?
