Iberian Spirea is a compact, deciduous shrub native to southeastern Europe and parts of Asia, growing 3 to 5 feet tall with an equal spread. In late spring, it erupts with showy clusters of small white flowers that appear on old wood, attracting butterflies and other pollinators. Hardy in zones 5 through 8, this low-maintenance shrub thrives in full sun with moderate water and tolerates drought, poor soils, and deer browsing, making it surprisingly tough for a plant this elegant.

Small oblong leaves stay neat and tidy on upright, spreading branches that naturally form a graceful silhouette without demanding constant pruning. Flowers smother the plant in May and June with a display dense enough to almost hide the foliage, and the shrub recovers quickly from light shearing to encourage repeat blooms. Its ability to handle drought, erosion-prone slopes, and complete deer indifference means you can plant it and mostly forget about it.
This shrub excels as a hedging plant, creating an informal barrier that needs only light annual pruning after flowering. Its ability to stabilize slopes makes it valuable for erosion control on difficult sites where more finicky ornamentals would struggle.
No timeline data available yet for this variety.
Prune each year immediately after flowering in June to maintain shape and encourage a second flush of blooms. Remove faded flower clusters through light shearing or selective branch removal. Avoid heavy pruning in late summer or fall, as flowers develop on old wood and late-season cuts will eliminate next spring's blooms.

“Spiraea hypericifolia hails from open forests and dry sunny slopes across southeastern Europe (historically known as Iberia), central Asia, southwestern Asia, China, Mongolia, and Siberia. Its toughness and ornamental value earned it a place in gardens worldwide, and it has escaped cultivation to naturalize in parts of Mississippi, testament to how well it adapts to new environments.”
