Well the folks have some wild sumac on the edge of the property. It usually flowers and has fruit on them all winter after they mature into fruit. This year all that remains on the flower spike it just that, the flowers have fallen away. I examined them and it appears that the flowers were only pollen flowers. There is no insects involved and the plants are healthy and green. Does sumac act like red maple, where it can have both flowers this year and the next might be male? There are other wild sumac down on the river that have set fruit and some also that only have a bare spike left. As I said earlier, these ones on the lawn have usually had fruit. I can't explain it, other than they must have only had pollen flowers this season.
