Why are blue flowers so rare?

Plants with cooler shades are rare in nature, whether you call their color azure, periwinkle, lavender, cerulean, indigo, blue or purple. The rarity is due to the way color is produced and how our eye perceives it. 

Blue is created when an object, or a flower in this case, produces molecules that only absorb very small amounts of energy. Blue purple flowers need to absorb all of the red spectrum and reflect only the blue light into the color receptors in our eyes.

When should I buy perennials?

Perennials are best planted in the early spring, allowing them to become established six to eight weeks before the summer heat kicks in. You can also plant perennials in the autumn, six to eight weeks before your ground freezes.
