Just a note. If the second one is a type of species Dahlia then it may
NOT have tubers, some varieties just have fleshy roots, but after the
first frost I would cut it back and lift it carefully to store somewhere
frost free.
Who knows next year it may flower and supprise us all.

Yep -- we fully intend to dig it up carefully when the time comes!
Interesting about the non-tuber varieties -- we'll remember that!
