Sylvia asked > Does anyone know of a list by genera, at least, of viability times for stored seed? I bought 100 seeds of Adansonia gregorii in the late 1990s. This is now renamed to something else I can't recall. It is the one baobab native to Australia, and grows in arid regions. I planted a fair amount of it when it had just arrived, gave some to friends, and forgot the remainder in a drawer. I discovered and planted what was left into a 5-gallon pot 6 years ago. They are still sprouting. One came up just a few weeks ago. Leo Martin Zone 9? Phoenix Arizona USA
