I used to send my plants north to test for northern hardiness but I haven't done that in several years, I have never sent any south but I have heard from customers in the south that have purchased some that many of my plants have rebloomed for them which is good to know. I guess if they have good bud counts in the north, they should certainly have better in the south. I just do not register any unless they have good bud count. I did register a couple with 12 buds but they bloom for a long period of time because buds don't develop real fast.
