I have a couple of Trident Maples growing in the garden and amazingly they are still in leaf in the middle of December. The second one was grown from a cutting of the first which was bought as a very young tree from Heron’s Bonsai about 8 years ago.
The original tree is being grown in a crowded be in a sheltered spot in the garden but the second is being grown as an ornamental tree near a North Facing Wall in a very cold and windy part of the garden. It really should have dropped all its leaves some time ago.
The original tree which has been cut back a couple of times and new leaders grown. needs looked at again.
Current leaf which looks pretty fresh
The second tree in the most exposed spot in the garden. Struck from a cutting about 6 years ago but was only planted out 18 months ago. Before that it had spent its life in a 12 inch pot and was totally neglected.
The tree wants to be a multi trunk. I obseved that in all the cuttings I took
