found in grounds of Tredegar House in Newport. Can anyone please tell me what tree this is from. Rose shaped cones.
No interactions present.
...without any sense of scale.
Just looking at them, I would have said possibly Larix kaumpferi (Japanese Larch) as they look like wooden roses.
But they would have to be small, 1" or less in height and width.
If they were more like 2-3" across, then they might be part of a Cedar, although the scales look too reflexed (out-turned) to be Cedar.
Cedar cones tend to be closer-packed, and with the tips of the scale curled inwards.
Sam, if you would like a less tentative ID, would it be possible for you to return to the site, and take photos of the tree under which you found the cones? They don't generally fall far from the tree. Pictures of the tree itself, the bark and the foliage would be helpful, along with a close-up of the foliage (with something like a coin to give scale, if you don't have a ruler) and the terminal buds. These things will all help give an ID.
How to take close-ups with cheap phone and hand-lens:
