The Big Idea:
Nonstop color from summer through fall defines the border planted on the south side of the pergola. Painterly sweeps of color inspired by English garden designer Gertrude Jekyll's techniques signify each season.
The Plants: 'Ryan's Yellow' mums run the entire length of the pergola, periodically punctuated by 'Rachel Jackson' asters. Both perennials were discovered and named by Ryan. The climbing aster at the far end adds color up high.
