My monkey puzzle appears to be one of what may have been a twin at some point. There's a stump beside it with the same bark. It's all dried up. Last month I noticed 2 male cones up near top. This tree has mostly female cones. And is producing multiple twin seedlings. Is this normal? My friend in Washington breeds them. He grows 1000's and gets mostly 2 cotyledons per seedling. He grew 3 out of 3500 with 3 cotyledons. And 1 twin out of 3500. He believes the 3 cotyledons indicate being female. And the 2 cotyledons being male? My twins mostly have 3 and 4 cotyledons. Does anyone think he's possibly discovered how to identify gender? Obviously, only decades would prove theory. But still, interesting observations.
