Pawpaw germination

On November 10, 2012, I placed three pawpaw seeds in three separate containers to begin the germination process. The pawpaw seeds had been in my refrigerator since around September 8. I buried the seeds about one inch deep in a twelve inch container, then placed them in the green house. Today, I unearthed all 3 seeds, and one of the seeds that I obtained from seed rack had already sprouted and was sending down a tap root. Yeah!!!
