I really like this combo — ‘Onyx and Pearls’ Penstemon (Penstemon digitalis ‘Onyx and Pearls’) with Mexican fleabane (Erigeron karvinskianus ‘Profusion’).
The dark purple penstemon foliage is such a good backdrop for all those loose little white and pink daisies. Both handle summer dry well and flower for a long period, but the foliage holds interest even when they’re not flowering.
