Paperbark maple = acer griseum.
??lacebark elm.
Go down to the statehouse sometime they have a lovely old lacebark elm.... it's on the State street side up towards High street.
I’ve read the germination rate of A. griseum is extremely low
To enhance germination, drench the soil in Humic Acid @ 28 grams per gal.It seems more specimens in the same area will enhance the possibility of fertlile seeds.
My favourite (very teliable, in the EU) online provider also states a rate of germination which is quite low.
So far, I've just sown 5 seeds from my own tree.
I don't think any of them will sprout, but I've just got some from other locations.
A two-year process ?...
