Anthony Waterer Spiraea

Sulphur-Flower Buckwheat is a native perennial wildflower known for its dense clusters of cream to yellow flowers. The long-lasting blooms persist from late spring into summer, providing an extended nectar source for a variety of pollinators. The flower buds are often red-tinted before opening. As the blooms age, they shift to orange or red, adding seasonal interest and making them well-suited to dried flower arrangements. Its seeds are also eaten by birds, adding to its ecological value.

Depending on climate and conditions, Sulphur-Flower Buckwheat may be evergreen to semi-evergreen, or its foliage may turn red during fall. Its deep roots and spreading growth stabilize rocky or sandy soils, making it useful for erosion control. Exceptionally hardy once established, it requires little care and thrives in challenging environments, making it an excellent choice for pollinator gardens, naturalization, and ecological restoration projects.

Anthony Waterer Spiraea is a low maintenance shrub with a dwarf, rounded form. In spring and summer rosy pink blooms emerge against green foliage. Its tolerance of a variety of well-drained soils makes it an ideal foundation, landscaping, or border plant.

If deer and rabbit are an issue on your property, consider planting Anthony Waterer Spiraea for its deer/rabbit resistance. Due to its compact form, minimal pruning is required.
