Growth Stages

1

Establishment

4-8 weeks

Newly planted shrub focuses on root development with minimal above-ground growth

Water frequently (2-3 times weekly) for first 4-6 weeks. Mulch around base. Avoid fertilizing heavily; use balanced slow-release fertilizer if needed.

2

Vegetative Growth

Spring through summer

Shrub develops branching structure with lance-shaped dark green leaves

Prune lightly after flowering to maintain compact form. Remove any dead or crossing branches. Water during dry spells.

3

Flowering

4-6 weeks, typically April-May

Fragrant, creamy-white bottlebrush-like flower spikes emerge from branch tips

Flowers attract bees and butterflies; minimal intervention needed. Do not deadhead unless spent flowers are unattractive.

4

Autumn Color

6-8 weeks, typically September-November

Foliage transitions from green to outstanding burgundy-red hues before leaf drop

Part shade can reduce intensity of fall color; full sun produces best color. Water if fall is dry.

5

Dormancy

November-March

Deciduous shrub loses leaves; bare branching structure visible

No watering needed unless experiencing extreme drought. Prune while dormant if needed. Mulch base to protect roots in cold zones.
