We have a few guys here with very old tridents and have been here for about 20 years or so.Now I only know of two japanese maples here one is in Miami Tropical bonsai and it was owned by the late Joe Samuels and has been here for about 8 years or so.The other is a japanese red maple and has been here for about 10 years and neither one came as young trees.The red one actually thrives a bit here,I got a yuri hime and it is a little experiment because I am learning how to use freezers and they both went dormant here with the freezers.The JM woke up a week ago and has foliage everywhere,the trident is just waking up.I will post pictures up in a few.they were both smaller last year by a lot.they grow a lot here and I hope they stay thriving.I am trying to be a little different here.I am not that fond of tropicals,lol.I have more azaleas than tropicals.I am a JBP man but I also have some tropicals like a ficus nerifolia that I am making into a shohin version of the cloud.Anyways sorry for the ramble and thank you all for your help.
