The Anthony Waterer Spirea is a radiant, easy-care perennial. Also known as Spiraea bumalda, this plant has narrow leaves that emerge with a slight pink hue in the spring before settling into a blue-green color. Flat-top flower clusters are a rose-red color and bloom in late June. The flower clusters almost appear to hover over the foliage.
This upright, mounded plant has a very dense growth habit. Use in a mixed bed or border or conceal a foundation. The blue-green foliage looks lovely when planted alongside an evergreen. This is a fast-growing plant, but it responds well to pruning, so you can ensure it will continue to fit a space by trimming back new growth. This beauty grows as a perennial in USDA zones 4 through 8.
Anthony Waterer Spirea Care
Plant this Spirea is full to partial sun. Soil should be rich and neutral to slightly acidic and well-drained. Routinely water for the first growing season, but established plants generally only need water during a dry period.
An application of a balanced fertilizer in the spring will get this plant off to a strong start. Trim as needed in the late winter or early spring.
Anthony Waterer Spirea Spacing
The Anthony Waterer Spirea is an upright shrub that will grow 3 to 4 feet tall and 5 to 6 feet wide. Plants can be spaced 14 to 28 inches apart.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
- When to Prune
- Late winter to early spring, before new growth starts
