That's 8 and 9 years of age. I suppose each species has it's own general life expectancy. It would be nice if a list of approximate life expectancies could be compiled for reference. About all I know for sure is that L. pumilum is short lived here of 4 to 5 years, so it's best to start new from seed every couple years. And L. henryi and L davidii are tough as nails and seem to live forever here. For everything else in between, I'm in a fog. I've kind of concluded that it's probably a good idea to scale every 4 to 5 years if possible. That way I could have young mature adult plants for pollination and seed.
