I believe that we've learned our lesson on planting monoculture street trees. It started with planting American Elms on every city block in the early 1900s, which were later wiped out by Dutch Elm disease, leaving many cities with treeless neighborhoods. Then we went to Green Ash, along with Canada, as a preferred street tree. In 2014, I saw block after block in Ottawa, Canada, that looked like a blast had occurred because the Emerald Ash Borer had killed all the mature Green Ash.
Around the time I started my career as a landscape architect, hybrid Pears and hybrid honey locusts were marketed in the profession as the perfect trees.
'Cleveland Select', 'Chanticleer' and 'Bradford' Pears were being pushed by every nursery because they bloomed early, had a long-lasting, glossy, green foliage that turned a brilliant red in the fall, and then had a decorative fruit that wasn't messy. Now, decades later, the weak, wooded Frankenstein tree has invasive, smelly, blooming offspring that sprout from seed and take over vacant lots.
The hybrid Honey Locust was perfect because it was tough and had fine leaves that didn't block sunlight, so a lawn could grow thick underneath it. The icing on the cake was that you didn't have to rake the leaves. After giving some nice yellow fall color, they fall off and blow away. Perfect, right? Wrong. I'm finding that even though they are supposed to be drought- and salt-tolerant, several other trees outperform them in urban conditions.
So now I'm making up for the hundreds of 'Bradford' Pears and 'Skyline' Honey Locusts that I have specified over my career. I bring a lot more diversity to my street tree planting layouts now.
I believe hybrid Honey Locusts are the only tree species in this entire commercial development in Beachwood, Ohio.
