What are the flowers on birch trees?
In addition to the exfoliating bark that offers year-round appeal, river birch produces showy, reddish-green, 2- to 3-inch long male (staminate) flowers called catkins at the ends of branches. They appear in late summer and autumn and remain on the tree during the winter. In the spring, when the drooping, dark brown pollen-bearing male catkins expand and bloom, separate, greenish, ¾- to 1¼-inch long non-showy female (pistillate) catkins emerge from shortened shoots called spurs. These upright female catkins resemble small pine cones. Birch trees are monoecious, meaning that male and female flowers are produced in separate structures on the same tree. The wind-pollinated female catkins develop into brown, dangling structures that bear many small, brown, winged nutlets, which are dispersed by the wind.

What is the aphid on birch?
In the spring, spiny witch hazel gall aphids that either overwintered as eggs on witch hazel bark ( Hamamelis spp.) or as immature females beneath the birch bark feed on the sap of newly expanding river birch leaves. Their feeding causes the leaves to become distorted. The puckered or “corrugated” upper leaf surface produces deep channels on the lower leaf surfaces where the aphids feed; they are further protected by a coating of waxy-white granular material. After several generations, winged female aphids return to witch hazel to complete their life cycle.
