Q.what type of japanese maple do i have?
I have a tree that is 30 years old. It has white bark, the Japanese maple leaves (serrated, 7 points). It is about 30 feet high, round in shape. The leaves are maroon and green, turn a burnt orange for a short time in the fall. I love it, my friend wants one, and I have no idea what type it is! It grew quickly, reached its size and has just remained so.
There are over 700 different Japanese Maple cultivators that are available to consumers.
It would be very difficult to give a specific name to your tree.
Do a Google search for a Japanese Maple grower and find a tree that meets the wants and needs of your friends garden.
