Root System For The California Pepper Tree

Question

i was curious about the roots for the California Pepper tree. is this a tree that can be planted close to a cinderblock wall that borders a backyard without damaging or cracking the wall?

Answer 1

This University of CA article doesn't sound encouraging. It says they grow up to 40 feet tall and have aggressive roots and drop litter. Some consider them an invasive weed.
