These trident maples started life from seeds thrown into this pot and then allowed to do their own thing.
Over the year they haven't done a real lot in sense of growing but they all have short internodes and now I know they all have red autumn leaves so that is good information. They are only 7 or 8 months old and I think the red autumn leaf colour is the best (some do have yellow leaves in autumn) and as such they may have a future.

Seems like quite a lot of growth to me. Looks great.

I am quite liking Tridents

I'm so jealous of your Autumn colour!

I have heard that tridents can vary their colour from year to year. Does anyone know if this is accurate or mythology?

I've seen it here, not that we get massive colour, but the different weather patterns will make a difference to the colour the trees produce. (My understanding, anyway.)

Must be this years seasons i have many young tridents that have the same colour tones, but older tridents are still green.

Autumn colour for most species varies depending on conditions. Cold nights and sunny days gives the best colour. Some years I get strong reds and yellows in the trident leaves while other years there are less reds. Occasionally the trident leaves just go brown and fall.

I've also noticed that individual plants can have different colors. Some of that may be genetic so different from one seedling to the next but it also appears that watering and pot size can also change autumn colour.
I nearly always see earlier colour in the smaller pots and in the larger groups in shallower pots. Trees that have not been repotted for a few years also tend to change colour earlier than those that still have ample root space.
Those factors lead me to think this earlier colour change may be related to water availability, nutrition or maybe root temperature.
I've currently got patches of colour in the nursery that's more closely aligned to pot size than species.
