Establishment
First growing season (3-4 months)Young shrub developing root system and initial branching structure
Water regularly during first growing season. Mulch around base. Stake if necessary for wind protection.
Vegetative Growth
Year 1-2Shrub develops arching canes and dense foliage; no flowers yet
Minimal pruning; allow natural arch to form. Remove dead or damaged wood. Fertilize lightly in spring.
Flowering
3-4 weeks in spring (April-May depending on zone)Abundant clusters of small white flowers densely cover arching branches, creating a cascading effect
Do not prune during or immediately after flowering; flowers form on previous year's wood. Deadhead spent flowers if desired.
Fruiting/Seed Development
Late spring through summer (May-August)Small capsule fruits develop after flowers fade; foliage remains green throughout summer
No special care needed. Foliage may turn reddish in fall. Seeds disperse naturally but rarely cause volunteer seedlings.
Dormancy
Late fall through early spring (November-March)Leaves drop in fall; bare branches provide winter structure and interest
Prune in late winter or early spring before new growth. Remove crossing or diseased canes. Cut back oldest canes to ground level annually.

Fun Facts
- 🌱 Bridal Wreath is actually a hybrid spiraea (Spiraea × vanhouttei) created in the late 1800s, combining the best characteristics of parent species for superior ornamental value.
- 🌱 The flowers form on 'old wood' from the previous year, which is why pruning timing is critical—prune immediately after flowering to avoid removing next year's flower buds.
- 🌱 Despite its delicate appearance, Bridal Wreath is one of the hardiest spiraea varieties and can survive harsh winters in zone 3, making it extremely cold-tolerant.
