Roadsides planted with native plants (in the US) have more bees.
Now, the article states that native plants "have deeper roots". Does this mean that plants native to the US generally have deeper roots than plants native to other areas, or does it mean that plants generally have deeper roots in their native area, or does it mean that imported plants to the US tend to not have deep roots? And, whatever the reason, why is that?
