Spirea (Spiraea spp.) is a group of hardy shrubs with 100 unique species. They often have colorful foliage and are covered in abundant delicate blooms. The genus name, Spirea, originates from the Greek word for “wreath.”

Spirea are native to Japan, China, and Korea. They are hardy to USDA Zones 4 – 8. They do best in full sun and are tolerant of a variety of soil types. Once established they are drought- and pollution-resistant, making them good choices for urban gardens.

Spirea are generally fast-growing and many are compact and mound-forming. If any pruning is needed, it is best to do so right after flowering. It is not necessary to deadhead them.

They are attractive to butterflies, bees, and other pollinators.

According to the National Garden Bureau, who has declared 2023 as the Year of the Spirea, the main varieties of spirea available commercially include:
- The Japanese spirea (Spiraea japonica), which are known for their wide flower and foliage color range, and their low-growing, mounding form.
- The Bumalda spirea (Spiraea x bumalda), which are similar to Japanese spirea, they are a cross between Spiraea albiflora and Spirea japonica. Flower colors range from white to deep pink.
- The Birchleaf spirea (Spiraea betulifolia), which are known for their larger, blue-green, birch-like leaves and stunning fall color.
- The Korean spirea (Spiraea fritschiana), which are native to forests, slopes, and rocky areas.
- The Vanhoutte or Bridal Wreath spirea, (Spiraea x vanhouttei), which are known for their vase-shaped habit, flowing, arching branches and cascading showy spring blooms.
