A short web search showed me that the tree grows to about 10-12' x 10-12'. It is recommended for bonsai, so it should take pruning. Figure half the width plus 2-3 feet away from the house. 6+3=9, 5+3=8, so 8-9 feet from the house.

I have one in my front yard. She is about 12 years old now. Probably about 8-9 ft wide and 7-8 ft tall. I do prune her each year to keep from out growing her space. The Star Magnolia is first to start blooming in my yard, then Snowfountain is second. Then the beautiful Yoshino Cherry. Love all of them. After a long winter, beautiful blooms are a site for sore eyes.

I've never been able to warm up to the Snowfountain. That drastic up-&-down growth pattern just looks weird to me. Perhaps if I were planting it in a Japanese garden I'd find it more appealing. But in the general landscape, to me it just looks like a tube - lol!!

My absolute favorite weeping tree is a weeping crabapple called "Louisa". It has a much more open, low, spreading, weeping habit, & is just SO very pretty. Flower buds start out dark pink - almost red - then open into 2-tone white-dark pink single flowers. In the fall, the tree sports small gold crabapples that the birds adore. What more could you ask for?
