About Sweet Viburnum - Knowledgebase Question

I am very interested in sweet viburnum because I need an evergreen screening hedge or tree along a tall fence (7.5 feet tall, 24 feet wide). Here are my questions.
1. Does monrovia produce it as a tree? If not is it easy to raise it as a tree?
2. In your catalogue you say the landscape size is 12 ft. tall, 8 ft wide is it the right size? I have read somewhere else the plant may reach 20'x15'.
3. How fast does it grow? How many inches can I expect per year?
4. I intend to plant it in front of a fence. From the fence to the sidewalk the room to plant is 10 ft deep 24 ft wide filled with lawn. Since the tree form seems to be multitrunks is it possible to train it to be as close as possible to the fence? This way I will have half of the tree inside my garden and half the tree outside toward the sidewalk.
5. Is it possible to raise it as a single trunk?
6. If you have any other plant suggestions that will match the narrow space I described above and a plant not as tall than 20 ft maximum your are welcome.

Viburnum awabukii is an evergreen shrub or small tree growing about 12' tall and 8' wide. You can expect moderate growth (up to 6-12" per year) from viburnum. Training to a tree shape is easy - simply remove all the growth along the main trunk, then rub out any buds that develop along the trunk for a year or two until the bark becomes thick enough to discourage additional bud and shoot development. It is possible to plant it very close to the fence, as long as you don't crowd the foliage on the top of the plant. You can train it to a single trunk by removing any shoots that appear from the roots or the crown of the plant, but it really is attractive when allowed to form multiple trunks. A tree form of Viburnum is grown by Monrovia and is available in 5-gallon containers. Good luck with your landscaping project!
