Bluebeard

Colorful Combinations

As one of the few flowering shrubs that bloom in late summer, bluebeard can be a valuable plant to add to your garden. Also called blue mist spirea, this deciduous shrub features long, graceful stems covered in small leaves. Those stems are loaded with blossoms at every leaf section when it is at peak bloom, which draws butterflies and bumblebees. There are many colorful foliage varieties to consider in addition to the familiar soft, silver-green version. Golden foliage is one of the most appealing; its bright yellow leaves create a stunning backdrop for the bright blue flowers. When bluebeard isn’t in bloom, the foliage adds a visual lightness to the garden.

Bluebeard Care Must-Knows

Bluebeard will not tolerate wet soils, so make sure it’s planted in a thoroughly well-drained area. If the soil stays wet, the shrub’s roots will likely rot. If these plants are too wet during the winter, they won’t come back in the spring. Once established, bluebeard is drought-tolerant.

Bluebeard thrives in full sun. Some of the older varieties of bluebeard can display a fairly loose structure of branches, but full sun ensures these plants are as dense as possible. Full sun is also ideal for the most impressive flower display; the less sun the plant gets, the fewer blossoms will appear.

The top growth of bluebeard is not nearly as winter-hardy as the roots. But bluebeard blooms on new growth, so this characteristic typically isn’t a problem. If you think you have lost your plants to winter, wait and watch for signs of growth at the base. For the most vigorous and compact growth, cut back the shrub each spring. Pruning encourages growth from the base and prevents plants from dying out in the middle.

New Innovations

Many of the new bluebeard varieties are dwarf in size, making them good choices for smaller spaces and containers. Other new varieties display colored foliage that won’t burn in the sun. There are also new and improved varieties boasting bigger and bluer blooms.
