In the spirit of the Independence Day holiday and just cuz it's fun to look at different and creative ways to combine plants, I've singled out three monochromatically-themed gardens: red, white and blue (with the colors loosely interpreted).
This is a recent addition to my photo archives—captured last weekend while touring Seattle-area gardens during the Hardy Plant Society's study weekend.
My travel-mates and I were enamored with this vignette, and surprised at how effective it was given its monochromatic theme—it relied on variation in plant form, foliage shape and texture, and of course the (very large!) pot made a strong statement. Adding to its charm, the foliage was backlit and radiant (my photo doesn't do that aspect justice).
This combo brings the heat like the glowing embers of (quiet and safely-managed 😜) fireworks. Red foliage contributed by Berberis thunbergii 'Orange Rocket' on the left and Cotinus c. 'Royal Purple' to the right.
This one takes the heat down a notch. This plant combination from the first incarnation of my parking strip garden couldn't be simpler—Rosa 'Iceberg' and Miscanthus sinensis 'Variegata' create a cool, crisp and refreshing scene.
The party really gets started with this one! Spotted at Floramagoria in Portland several years ago, this floral eruption is a delightful jumble of starbursts, spires and sparklers in shades and shapes of blue (okay, sure, a purple-y blue... but blue). Perennials include: Salvia n. 'Caradonna', Allium christophii, phlox, a blue-flowering hardy geranium with yellow foliage, Astantria m. 'Hadspen Blood' (or similar), and more.
