Sea Holly Seed Cone Sea Holly produces a brown central cone when the seeds are mature. With you thumb and forefinger carefully pull the cone from the plant stem. If it is ripe it will come away easily, having to tug at the cone in order to remove it signals that the seeds are not mature yet.
Allow the cone to dry for a few days in a warm place. Press it between your fingers with a rubbing motion and the cone will break apart into many seperate parts, these small brown parts are the seeds themselves. Visually they appear shaped like small arrowheads with a bit of fringe on the wider end, or, more imaginatively, they look like very tiny tan shuttlcocks for badminton.
