Blue Mist Spirea, light green with powdery-blue flowers

Discover More Information On Blue Mist Spirea

Are you looking to add season-long beauty to your open spaces? The Blue Mist spirea (Caryopteris x clandonensis ‘Blue Mist’) can provide your landscape with a little charm. This gorgeous flowering shrub puts on a show all season long. The Blue Mist spirea makes a perfect addition to those spaces that need an extra pop of color.

Plant Attributes

The Blue Mist spirea is also called the Bluebeard, and it is a low-mounded, deciduous shrub prized for its late summer flowers and aromatic scent. The blooms have a slight resemblance to blue clouds or mist. This flowering shrub keeps its mounded form throughout the year, and it grows to a height of 3 to 5 feet.

The flowers are 2 to 3 inches in height and width. Along the length of the stems, you will find panicles of these small clustered blooms. Its oval green leaves produce an aromatic scent when you brush them with your hands. These blue flowers bloom from the late summer into fall. When other plants have finished blooming for the season, this hardy choice continues to add color to your outdoor spaces.

Blue Mist spireas are known to attract local pollinators in your yard. You will notice an abundance of butterflies and bees heading to your landscape to sip on the nectar from the feathery blue blooms.

Landscape Use

These Blue Mist spireas are well-known for their low maintenance and high visual impact in a landscape. In those high-profile areas, the Blue Mist spirea shines with its silvery-gray leaves and fresh-smelling perfume. With its tight mound of foliage, the Blue Mist spirea presents a soft and polished appearance. You might want to add these magnificent plants in a row to create a low, solid hedge for your landscape. They make the perfect addition as a border for a driveway or walkway.

They can fill out those bare spaces throughout your property. You want to space them about 18 inches apart from the center. As the shrubs develop, their branches will grow together as you are left with a bounty of featherlike blooms and stunning foliage. You can use them in those sunny garden beds for an attractive element. In those mixed garden beds, the Blue Mist spirea pops with a beautiful blue color.

Since they are known to produce sweet nectar, the Blue Mist is an exceptional choice in a pollinator garden. If you pair them with early and mid-season bloomers, you will have bees and butterflies flocking to your yard throughout the year. The Blue Mist spirea can excel in an outdoor container. They will make a fabulous addition as a thriller in the center or act as a filler around the pot.

Planting & Care

The Blue Mist spirea doesn’t have any special needs for its maintenance. However, you will still have to meet a few demands. If you are looking for the best result, plant the shrub in an area with full sun. They need at least six hours of sunlight per day. This spirea should be planted in space with well-draining soil. If your soil tends to stay soggy, then it would be best to create a raised bed to elevate the Blue Mist’s roots. These spireas thrive in USDA hardiness zones 5 to 8.

When your Blue Mist spirea is young, you need to water it on a regular schedule. Once the roots have been established in the soil, they can become very tolerant of droughts. However, you should provide supplemental water during those long dry spells.

If you want to prune the Blue Mist spirea, it should be done after the harsh winter season. In the spring, you will want to prune it back to the ground before the growing season. The Blue Mist spirea often behaves like a perennial as it regrows from the roots every year. You can trim this shrub back and wait for the new flowers in the late summer.
