The photo above includes 'LeVern Friemann' lilies, 'Big Blue' salvia, 'Penhill Dark Monarch' dahlias, 'Seniors Hope' dahlias, 'Berry Awesome' hibiscus, plus Russian sage, 'Royal Purple' smokebush and 'Jeana' tall phlox at the back of the bed.
The 'Penhill Dark Monarch' flowers were huge and saturated with deep pink color. The tall plants needed better staking so they didn't lean forward as much, but they produced quite a few flowers as they flopped all over the other plants.
Here's another shot of 'Seniors Hope' and one of my three 'Berry Awesome' hardy hibiscus plants. My hibiscus plants weren't fully mature yet, but last summer they produced showy flowers for several weeks. Each bloom lasted for just a couple of days, but there were many buds on each stem. The leaves on this cultivar were tinged with mauve and maroon, so the plant was showy even before the blooming started. I highly recommend it.
The dark centers of the hibiscus echoed the color of the 'LeVern Friemann' lilies and the 'Florentina' climbing roses growing on teepee supports. Towering mauve 'Jeana' phlox was a very long blooming backdrop for this bed, and the lavender spikes of Russian sage made a nice contrast during its shorter bloomtime. The maroon leaves of the 'Royal Purple' smokebush at the center of the bed provided interest even when fewer flowers were in bloom.
