There are several ways to cool off a garden visually. The use of variegated foliage, white blooms, no blooms (just green foliage), and cool colors like blue and purple, are a few ways.
In my garden, for a visual cool, purple reigns:
|Crape Myrtle 'Muskogee'
|Scabiosa (Pincushion flower)
|Indigofera decora (Chinese indigo)
|Rose 'Popcorn' is weaving itself through the Chinese Indigo!
|This little aster is reminding me that soon the weather will be cooler, too!
How do you visually cool off your garden?
