Starting in June, you'll find the plants at nurseries, usually in 1-gallon cans (though the best selection of dahlias is available in spring, when you can plant them from tubers).


These daisylike flowers are available in lavender, pink, or white. Three varieties we like: A. cordifolius 'Cape Cod' (Sunset climate zones 1-10, 14-21), A. c. 'Little Carlow' (zones 1-10, 14-21), and A. novi-belgii 'Melody' (zones 1-24).

Penstemon (P.  gloxinioides)

These bushy plants are fairly short lived, but to make up for it, they produce lots of trumpet-shaped blooms over a long period.

Deep purple ‘Midnight’ and scarlet ‘Firebird’ are standouts for their vivid, south-of-the-border colors. Pink and white ‘Appleblossom’ looks fresh and springlike.
