Trident Maples.....I think I am beginning to like them.

Here I can not really grow Pine and Juniper -like trees because it gets too warm in summer and not cold enough in winter. I also did not like to grow Maples because my first one suffered all the time.
This is my first one....I still have it and it does not look much better now:

It also seemed that our temperate climate did add to the frustration of lack of color on Maples in autumn. Last autumn(2013) this changed and I had some lovely clors on my Maples:

I also got some field grown trees for cheap in August 2010. I bought 5 of them. From the time I bought them they did not grow much, but they are progressing.

Here is the first one:

I will let it grow out again this growing season and some further branch selection - I do need advice on this!
