Cool 20 years old and still viable. Fair bit of variety in Jamaican genetics, I actually have some beans from Orange Hill area that are about the same age. I haven't tried to sprout any though. I keep them to remind me of my first trip to Jamaica where I had a variety of experiences good, bad and strange. I would love some fine Lambsbread (Lambsbreath?) sativa mon. Some of the greatest (and crappiest) weed I ever tried came from that island.
