I talked to his wife and she said it was just one day he got up was in a great mood and said good bye to his wife, went to work. At work I guess his heart just stopped (Sudden Cardiac Arrest) and he was dead before anyone knew what had happened. He had always been it good shape and had no previous heart problems.
None of the plants are available for trade at this time, his wife wanted me to hang on to them for a while. If everything goes well I should have plenty to trade in a year or so.
