4-8 weeksYoung plant developing root system with initial leaf growth; stems may be thin and spindly
Water consistently, stake if needed for support, protect from extreme wind. Keep soil moist but not waterlogged.
Vegetative Growth
6-12 weeksPlant develops bushy, branching structure with lush green foliage; stems thicken and woody growth begins
Light pruning to encourage branching; remove any flower buds that form to redirect energy to growth. Apply balanced fertilizer monthly.
Flowering
8-12 weeks (repeats throughout season)Long, slender panicles of pure white flowers emerge from branch tips; blooms appear in successive waves
Deadhead spent flower spikes to encourage continuous blooming. Water during dry spells. Feed with bloom-boosting fertilizer (lower nitrogen).
Peak Bloom & Pollinator Activity
4-8 weeks per flushMultiple flower panicles in full bloom simultaneously; butterflies and other pollinators actively visit
Minimal intervention needed; enjoy the display and wildlife activity. Water only if drought conditions occur. Deadhead regularly to extend blooming.
Dormancy/Winter Rest
12 weeks (November-March in cold zones)In colder zones, foliage dies back or drops; stems remain visible and may be cut back or left standing
In zone 5b, mulch heavily around base for winter protection. In warmer zones, perform dormant pruning (late winter) to maintain shape. No watering needed.

Harvest Tips
Flutterby White is an ornamental shrub, not harvested for food or medicine. Cut flower spikes for fresh arrangements by snipping just below the lowest open bloom.
