Maple Budding

Hey there guys Just a general question really i read that Trident maples are the first to bud out in the spring. Can anyone tell me if this is true? Im asking because i have a Red japanese maple and two Tridents. The tridents still have not pushed out the new growth yet, while the japanese maple is already pushing new growth. Im not really concerned about this more anxious than anything to see signs of life any thoughts on this?

Hi Steve,
I have a small Trident that leafed out along with my other mountain maples, but my large Trident was some weeks later.
I think it's down to individual trees and where the're sited in your garden.
