Street Tree Project
Out of the five trees that I have observed, I would pick the apricot trees leaves as toilet paper if I truly had to resort to that.
On the other hand I do think that street trees make a neighborhood more pleasant to look at because it adds a softness to the harsh texture of the homes in the neighborhood. They also add both some beauty and color to the neighborhood.
One pro to planting non-native plants in our cities is that it provides some diversity in the plant population in that area. One negative is that the non-native plant may not survive in the location that it is put in.
