Wow, really amazing collection, not just quantity but quality. To my, mostly untrained eye, it is all very great looking, and to begin with, even better!
I really like maples, and your Japanese maple does look to have a really great trunk, measurement-wise. Maybe just personal liking.
My maple felt off its perch this morning in high winds, first time ever had something like that happen.. It somehow landed on its pot, upright, but had a load of soil chucked out, but seems to be no branch damage, which is the most important thing.
Hope to see more of you on the forum.
