Wht are some drawbacks for the "forrest pansy" tree (aka redbud)?

Redbuds are one of my favorites as they are usually the sign of spring here in TN as they bloom before most other trees. The only drawback on these I have seen over the years it their propensity to grow multiple trunks or large branches close to the ground which eventually split. This is one reason pruning is key. Make sure to trim off any shoots that appear at the base especially when the tree is young. You may also remove any branches sprouting out in the first 4-5 feet just to keep the tree in good form.
