Does the narrow sweet gum cultivar that has less fruit still attract as much wildlife as the regular sweetgum? I live in Center City and need to replace a Sophora with a tree without a large canopy. I would like to be as helpful to the birds and insects as possible. What are your suggestions? I love Redbuds but I read that they are short-lived. Is this true?
It sounds as if your space is limited so I recommend using a narrow fruit tree such as Prunus serrulata`Amanogawa`as it provides flowers and small black fruits attractive to birds.
