Establishment (Year 1)
First 6-12 monthsYoung shrub with sparse branching and modest foliage development
Water regularly to establish deep roots. Mulch around base. Prune lightly to encourage branching structure. Stake if needed in windy locations.
Vegetative Growth (Year 1-2)
6-18 monthsShrub fills in with dense green, deeply lobed foliage; branches become woody and strong
Continue regular watering during dry periods. Apply 2-3 inches of mulch. Prune in early spring to shape and remove dead wood. Minimal fertilizer needed.
Flowering (Late Summer to Fall)
6-8 weeks, typically July through SeptemberTerminal panicles of fragrant, small flowers bloom in shades of lavender-blue, purple, pink, or white depending on variety
Deadhead spent flowers to encourage additional blooming. Ensure adequate water during dry spells. Light feeding with low-nitrogen fertilizer can enhance blooms.
Fruiting (Fall)
4-8 weeksSmall, dark berry-like drupes (fruits) develop where flowers were; can persist on plant into winter
Leave fruits on plant for wildlife benefit or ornamental interest. Can collect seeds for propagation if desired. Avoid heavy pruning.
Dormancy (Winter)
3-4 monthsDeciduous varieties lose foliage; semi-evergreen types retain some leaves. Plant appears sparse and bare in cold zones
Minimal watering. No fertilizing. Prune any damaged branches. In zones 6-7, protect young plants with mulch mound over crown. Wait to prune major branches until spring after last frost.

Dry leaves and flowers in a warm, well-ventilated area away from direct sunlight. Seeds can be collected in fall when fruits turn dark and dry; shake branches onto a cloth to collect.
