Stay Cool With These Blue Flowering Plants

The color blue is equated with cool temperatures. Water is often depicted as blue. The sky is blue.

Blue is also calming. Seeing blue relaxes the mind. It is soothing.

When used in the landscape, blue tends to draw the eye out, making spaces feel longer.

Interestingly enough, only ten percent of all flowering plants on earth are blue. So, enjoy these 11 as you consider them for your garden.
