hibiscus seeds?
Answers:
If the flower is spent and dried-- there should be a pod at the end of the stem-- take the dry pod and using your other hand, rub the palms together-- you will find debris from the pod and seeds-- the larger seeds seem to be the best to start. If you have a few months before really cold weather-- you can plant the seeds (marking the spot) and see how many come up--if they are hardy hibiscus-- just cover them with leaves before cold weather (assuming you are near zone 7).
I just harvested some from the church garden-- and I'll do the same.
good luck

Tiny specks ... doesn't sound like seeds to me. Maybe your Hibiscus is a hybrid and doesn't set seed?
