Kansas is warm (ie, hot) and muggy in summer, with it's fair share of wind, not exactly conducive to Japanese Maples. So, I'm trying to find a list - if there is one - of maples that are known to do well in these conditions. Specifically, I would love to find out which cultivars were propagated/named/introduced by Harry Olsen and Harold Johnston. I know they introduced several maples and, seeing as they are both from the southeast - hot, humid, and lots of sun - it stands to reason that most, if not all, of their introductions would do well in those conditions, and therefore in Kansas. Other nurseries/propagators that I am not aware but are also in the south/east, and cultivars they've introduced, would be nice too. I do have Vertrees' latest edition, which I know does occasionally mention who introduced a particular cultivar, and whether it's heat tolerant/hardy, but not always. Can anyone help me out?
