I have at least 3 staghorn sumac (some suckering) about 10’ tall. I’m not sure of their age but the home is 20 years old. They seem healthy and produce blooms. On one plant, there are the cone shape pink blooms but on the other two , the blooms are a similar shape but actually larger, not fully developed and are a milky color.I understand there are male and female plants.

Can you tell me what might make the difference in blooms on the various plants? I saw these same blooms last year.

Thanks!
