Ash questions

m pretty sure I have Green Ash (Fraxinus Pennsylvanica) trees in my back yard. I say pretty sure because the serration in the leaves is very subtle and also I have not witnessed these two trees produce seeds/smaras in the 4+ years we have lived here. Could they both be male? Are these in fact green ash trees and what could I look at perhaps that might shed light on the cultivar?

Also the crotches have "mounding/ridging/bark accumulation" (not sure of the term) in them and I have not been found pictures of this online anywhere. Not like people are snapping pics of Ash crotch on a regular basis I guess! I find not only the bark but this crotch growth quite unique and have grown very fond of these trees and the aesthetic impact they provide. Is the crotchal activity normal and what is it called?

Back story is that they were planted by the home building contractor that constructed my neighborhood. My home is ~22 years old so I assume these Ash trees are roughly that age as well.

I'm thinking Fraxinus americana, check that one and see if it fits.

Those are some pretty sexy crotch shots. Maybe you should have put some bikini bottoms on them first.

That would be good but heres what I thought was funny!

But being serious now, I think your right. The reason I thought it was a Green ash was because thats what an Arborist told me, whoops!

The leaves dont have wing tips at the base, and after watching a video about White Ash ID, I found that Whites have U shaped leaf scars and Greens generally have D shaped leaf scars.

I'm thinkin these look like U's.

Heres a good link showing the leaf scar difference between the two.

Now for sure im thinking its White.

RE: Ash questions

Anyone second the White Ash ID from the leaf scars or if the crotch growth/collars are normal or perhaps a sign of something bad?

"I'm thinking Fraxinus americana"

You will know by the fall color if you can't determine by leaf scars or trunk appearance. Green ash turn a nondescript yellow and drop very quickly. White ash have a redder and much more attractive fall color.

RE: Ash questions

As for the collars, don't know if it's bad or not, but I have a couple ashes I let grow from stump sprouts that are growing rapidly and producing crotches that look just like the ones in your pic. Mine are green ash, though.

IME, ash trees are prone to splitting and losing limbs in thunderstorms. Quite possibly, this is related to crotches that began like the ones in your picture but I certainly do not know for sure
