Walking along the Book Hill section of Wisconsin Avenue in Georgetown, I crossed the street to take a few pictures of this arrangement. It wins my own “best in mums and sweet potato vines” award. (There’s a little English ivy in there too.)
It’s appropriately in front of an antiques shop that sells mid-century modern furniture.
I also liked this planter made from old roof tiles at Marston-Luce a few doors down.
And I love the frog.

weeks of dying mums to second the motion.— Lance Larsen, from “Backyard Georgics“

Ah, Marston-Luce, another shop that’s long been on my list of places to visit. The sweet potato vine keeps the mums from looking so “fake” which they often do as they’re so hybridized. And I love the chair just visible in the antique shop window.
We’ll have to go together someday. . . I thought the planter arrangement looked as sleek and modern (yet also “retro”) as the store and its wares — great design.
I love this part of Georgetown and was in David Bell Antiques last time I was in DC (in March for a Dumbarton Oaks Symposium) Not too far from here is a wonderful garden art shop.
