Seeds sit inside small, reddish fruits, and they germinate best if sown fresh, so clean seed and sow it in pots of free-draining compost in autumn, then leave them outdoors through winter, or chill them briefly first. Sow the seeds evenly over the surface and cover lightly in a loose, well-drained seed compost, keep the sowing evenly moist, and give the pot or tray full sun. Transplant the sturdiest seedlings to their permanent spots and let them develop without disturbance.
