Is that 5-6ft tall or wide? Also what color leaf, green or red?

You can also go to World Plants website. They have lots of pictures of different maple that are available which might help you decide what you like.

I saw one of these in a nursery today and would love to get it for our patio garden, but it would have to be planted in a container. The site gets filtered sun, and in spring and summer, some direct morning sun.

Would this tree stay small enough to stay in a large container in this site?

What are the spring and fall colors like? Right now the leaves are a beautiful bright green, and the shape of this particular tree is just gorgeous for up-close viewing.

I'm so tempted to buy it (as my early birthday present?!) but I'm afrid it might get too large for a container and a roofed patio. (The patio is open on two sides and the roof is made of semi-clear fiberglass, so it does get light and air.)
