Growth Stages

1

Establishment

First 1-2 years

Young shrub with developing root system and initial branching structure

Water deeply and regularly. Mulch around base with 2-3 inches of organic material. Protect from harsh winds in first year.

2

Vegetative Growth

Years 2-3

Shrub develops fuller branching structure with lush green foliage, typically reaching 3-8 feet tall

Maintain consistent moisture. Prune lightly after flowering if shaping is desired. Minimal fertilizer needed if soil is amended.

3

Flowering

4-6 weeks in late May to June

Produces abundant fragrant white flower spikes (racemes) 4-6 inches long in late spring to early summer

Do not deadhead if you want seed development and bird food. Flowers attract pollinators and beneficial insects.

4

Fruiting & Seed Development

Summer through fall

Develops small capsule fruits that persist on branches; foliage begins color change in fall

Leave seed heads for wildlife food and winter interest. Minimal intervention needed.

5

Fall Color & Dormancy

September through March

Foliage turns vibrant red, burgundy, or purple; plant goes dormant over winter

Enjoy fall color display. Leave standing for winter structure and wildlife shelter. Prune in early spring if needed.
