There is a Scottish poet/ sculpture /gardner that works in landscapes-- and by that i mean uses natural elements to compose artistic experiences that move the observer as would a poem: Ian Hamilton Finlay- worth spending time with I thik. Point being... the ash tree has a presence that took me back to childhood... to sunny mornings and grass clippings, warm dirt in the alley and morning glories trelling a chicken wire fence..... a benign canopy that both sheltered and connected me to the sky above.
