Fun Facts
- 🌱 Spirea Bridal Wreath gets its common name from the tradition of using the flowers in bridal bouquets and wedding decorations, symbolizing virtue and love in the Victorian language of flowers.
- 🌱 Unlike many modern Spiraea cultivars that flower on new growth, Bridal Wreath blooms on old wood, so pruning must be done immediately after flowering to avoid removing next year's flower buds.
- 🌱 The scientific name 'Spiraea' comes from the Greek word 'speira,' meaning 'wreath' or 'spiral,' referring to the traditional use of the flowers in wreaths and garlands dating back to ancient times.
