Kentucky coffeetree (Gymnocladus dioicus)

Fruit and Seed



Propagation Method

Seed collection: Kentucky coffeetree fruits are pods. The pods can be collected any time after the pods turn from green to tan, but they will naturally fall from the trees in late winter or early spring.

Seeds are removed by breaking and peeling away the outer pod wall. Inside the pod surrounding the seeds is a sticky or dry jelly-like material. It contains toxic materials that should not be eaten. Discard misshapen or off-colored seeds. Seeds can be stored dry for long periods in the refrigerator.

Seed dormancy: Kentucky coffeetree has physical dormancy.

Seed germination: Scarify seeds to break physical dormancy and allow water uptake. Following scarification, sow seeds in a nursery container to produce a seedling or sow them in a plastic container in the classroom to observe germination.
