Scarify the hard seed coat with sand-paper, rubbing the seeds until a small amount of white begins to show. Place the seeds in water. The seeds will begin to swell over the next few days, and soon will sprout. Once the seed sprouts, plant it just under the surface of the soil, in a pot. Gently submerge the pot in water, with the water level about 1-2" above the soil level. The leaves will form over the next few weeks. Plant in larger containers as the plant grows, and plant outside when the weather permits, after the change of frost and cold weather are far gone.
