Japanese Umbrella Pines (Sciadopitys verticillata) are occasionally found in my area as an ornamental tree, but are scarce and unusual. I'm not sure why. Right now, I only know of one, which is growing on the grounds of a suburban library. It was evidently planted 5 or 6 years ago when the grounds were renovated and landscaped. I'm wondering, is it likely that this tree will ever produce seed "cones" ? It's the only one in the vicinity. It seems to be doing well.
