These may be from the Sweet Gum tree (if they are loose). Hard to tell by the photo if they are loose or growing on a vine. We have 2 sweet gums in our yard and they start producing bright green pods this time of year that eventually turn brown, fall and make a huge mess come autumn/early winter.
@cimes1 They are definitely from a tree with needles, not leaves like a sweet gum tree. I'll ask our grounds manager if I see her. She knows everything!
Love all the patterns they create! Nice shot. The "needles" sort of look like a cedar tree- but I don't remember if I've ever seen the cones, so that's a wild guess.
Great picture of the mystery cones...tried to find out on the web but couldn't find any cones that look like that..interesting though. hope someone here on 365 will have an answer for you.
