Backyard Nature: Beech drops drop in

by Marlene Berlin

In the fall, as acorns rain down on our heads and mushrooms abound, another rather strange plant pops up: the beech drop.

Beech drops don’t get their sustenance from chlorophyll. They are parasites that develop a structure called a haustorium. It grows into the beech roots to siphon off nutrients.

For pollination, beech drops rely on a specific species of ant – prenoleppis imparis, or winter ant. They attract other pollinators as well. I saw a small bumblebee hopping from flower to flower – and not just any flower. The bee was going from top to top. The top flowers on these plants are cross-pollinating. The lower flowers are self-pollinating.

Once your eye knows what it is looking for, you’ll see beech drops all around Rock Creek Park and our yards.
