I think the common name for Picea rubens is Red Spruce.

Not Blue spruce or Colorado spruce or eastern spruce?

I agree; I've always known P. rubens to have the common name of Red Spruce. I found Red Spruce (Picea rubens 'Pocono') in the database and gave a thumbs up so that the common name Red Spruce shows up but I wonder if an administrator can just remove the selection for the common name Blue Spruce?

I removed it.

Colorado spruce should also probably be removed.

Can do (and did)!
