For brilliant gold foliage that stays bright all Summer, the aureate forms of Scots elm and paper mulberry are unsurpassable. The mulberry adds unusually shaped foliage, each leaf of which is mitten-like but variable: Sometimes there's one thumb (and on either side), sometimes two, and sometimes none.
This is not my original mulberry, which is about eighteen feet away. And yet, here it is, sprouting up through the wide joints between the terrace's dry-laid slabs. How did it arise?
