The authority on color, Pantone is kicking off the new decade with Classic Blue as its color of the Year for 2020.  The experts say that classic Blue brings peace and tranquility to the garden.  Blue plants are the rarest color in horticulture but certainly a fun color to explore in the garden.  Now that Pantone, the institute that sets the color trends for product developers across multiple industries, has announced that Classic Blue is the Color of the Year, you’ll start noticing this hue in fashion, home furnishings, industrial design, auto industry, as well as the garden.

Pantone says that the color is suggestive of the sky at dusk.  The reassuring qualities of Pantone 19/4052 Classic Blue instill “calm, confidence, and connection”.  They suggest that the blue hue “highlights our desire for a dependable and stable foundation on which to build as we cross the threshold into a new era.”

Blue Plants are the Rarest Color in Horticulture

We had a hard time coming up with a list of ‘true’ blue flowering plants but there are definite plants that would fall into the “almost” blue category.  Many blue flowers lean more toward the purple than a true blue.  Did you know that blue adds a touch of calm to your garden?

Some of Our Favorite ‘Almost’ Blue Plants

Salvia ‘Black & Blue’ - have bright cobalt blue flowers and attract birds, butterflies and hummingbirds love them.   These easy-to-grow salvias tolerate partial shade, so they are perfect for tucking into shadier spaces where other salvias don’t thrive.  Their flowers contract sharply with the black stems in summer.  They are heat and drought tolerant.  Flowers appear on spikes to 15” long over a long mid-summer to fall bloom.

Hydrangea macrophylla ‘Let’s Dance Rhythmic Blue' – Small (2’-3’) plant that can fit into any garden.  Flowers can shift from deep pink to vibrant blue depending on how you treat the soil.  (Adding aluminum sulfate to the soil encourages blue flowers).  Or just enjoy the pink/blue/lavender colors.  It’s wilt-resistant, stays tidy, likes moist soil and protection from the hottest afternoon sun.

Double Play Blue Kazoo spirea –  an easy to grow shrub with blue foliage and white flowers.  Requires minimal care.  Grows well in lightly shaded conditions (4 to 6 hours of sun or filtered light all day).  Not fussy about soil or watering.  Needs so special pruning or other maintenance to keep its good looks.
