Black Mulberry growing

[jennym]

Does anyone grow Black Mulberry? I've seen adverts for trees to buy, I've seen the real thing growing, beautiful (but big).
If anyone has experience can they answer these:
Are they slow to fruit? Can they be grown successfully (that is to fruiting stage) in a container? What yield can you expect from a tree say, 10 years old?
