Answer: This is taken directly from Monrovia's website description of the tree: "A selection that does not produce many seed balls!" If you want absolutely no seedballs, this tree may not be the best choice for you.
I'm not sure why the website and tag don't match. However, Zone 6 has average annual minimum temperatures of minus 10 to 0 F; Zone 5 is minus 20 to minus 10. What are the temps. in your particular microclimate? Temps. can vary quite a bit within short distances in the west because of geography. For example, since cold air drops, if you are located at the base of foothills, you're more likely to experience colder temps. than nearby flat areas. If you haven't tracked temps. in the past, it's a useful thing to do if you like to try a variety of plants. Check with local garden clubs or neighbors who might have this info. Good luck!
