Some ancient and familiar silhouettes line the serpentine. The ancient tree species I love tend to have conveniently recognisable shapes. The "billowing column" almost always means Taxodium distichum (the Bald or Swamp Cypress - in nature they form rather different shapes as they tend to form stands rather than grow in isolation).
It also colours a spectacular burnt orange when autumn arrives. This makes those jade green cones rather stand out.
A spiky "star shaped lolipop" profile means Ginkgo biloba
and Ginkgo biloba means an autumnal gift of a thousand golden crowns....
