Late spring through late summerSmall ornamental seedheads follow flowers; plant refocuses energy into foliage and branch development
This is the ideal time for pruning to shape the plant. Light summer watering as needed. Plant transitions to semi-dormancy in late summer.
Dormancy

Fun Facts
- 🌱 The genus name 'Spiraea' comes from the Greek word 'speira,' meaning 'coil' or 'wreath,' referring to the flower clusters. Reeves Spirea was named after John Reeves, a 19th-century plant collector and horticulturist who introduced many Asian plants to Western gardens.
- 🌱 Reeves Spirea is so floriferous in spring that the white flowers can completely obscure the foliage, creating a stunning 'cloud of blooms' effect in the landscape.
- 🌱 This shrub is extremely adaptable and can tolerate poor soil, pollution, and urban conditions, making it an excellent choice for difficult planting sites and coastal gardens.
