My most recent attempt: 6 seeds, soaked for about 5 to 6 hours in a solution of warm water and H202. Put in paper towel in baggie, and covered to provide darkness, set in warm location. 5 days later, signs of mold (!), but one seed with tail. Rinsed it off in a bit more water with H2O2 and planted in small pot. It broke ground today! Not sure now if that was two or three days after planting.
