If you have a garden which is very hot in the daytime, blue is the flower you can use for a feeling of coolness. Blue flowers are rare in nature which makes them extra special in the garden. In history the color blue stands for loyalty and faithfulness, but overall it gives one a feeling of calmness, serenity and peace.
There are many shades of blue from royal blue to robins’ egg blue. Blue mixes in very nicely with other colors in your garden landscape. Cooling blues give your flower beds dimension and depth.
Here is a useful list of beautiful blue plants:
Brunnera, Forget-me-nots, Hydrangea, Bachelor’s Button, Lobelia, Delphinium (must be staked!) Globe Thistle, Sea Holly, Himalayan Blue Poppy and Pulmonaria. Some columbines, phlox, asters, salvia and iris are almost blue as well.
There are also two grasses with a blue hue:
Blue Fescue and Oat Grass.
Grey-blue boulders or path stones can accent these sky blue colors. Coral tones go excellently with blue as well. So if you are feeling blue, go shopping at your local garden centre and do something about it!
