What is the most popular spirea?
Perhaps the most popular types of spirea are ‘Triumphans’ (Spiraea billardii), a magnificent summer blooming shrub with dark pink blossoms, and Bridal Wreath Spiraea (Spiraea prunifolia). Bridal Wreath grows 5 to 6 feet (1.5-2 m.) tall and can make great hedge plants with their romantic white flowers.
Should you cut back spirea every year?
Spirea bushes with red fall foliage and dead flowers blossoms are ready for a prune. Plan on pruning a spirea bush at least twice a year. Regular, scheduled trimming promotes good health and new growth. Removal of dead or excess branches allows sunlight better penetration to the interior and lower branches.
What looks good next to spirea?
They look especially good paired with bigleaf hydrangeas. Or set them near clumps of hostas that will take some sun. Since spirea blossoms are mainly flat clusters, contrast the flower shapes you plant nearby. Narrow purple spikes of salvia or upright plumes of astilbe add nice variety.
