Establishment
First year after plantingYoung shrub developing root system and basic branch structure; minimal flowering
Water regularly and deeply; apply 2-3 inches of mulch around base; avoid heavy pruning; stake if needed in windy areas
Vegetative Growth
Spring through early summerShrub builds branch framework and foliage; slow to moderate growth rate; leaves emerge in spring after flowers fade
Light pruning to shape; maintain consistent moisture; apply balanced fertilizer in early spring; remove any frost-damaged wood
Flower Bud Formation
Late summer through fallFlower buds develop along branches during late summer and fall; buds remain dormant through winter
Do not prune now as this removes flower buds; reduce nitrogen fertilizer to encourage flowering over vegetative growth; maintain moderate watering
Winter Flowering
December through FebruaryFragrant, pale yellow flowers open on bare branches during coldest months (December-February depending on zone); flowers may last 4-6 weeks
Enjoy the fragrance; monitor for any damage from harsh cold or snow; no pruning during flowering; cut stems for indoor arrangements if desired
Post-Flowering
March through MayFlowers fade and drop; foliage emerges; shrub returns to vegetative growth; small seed pods may form
Resume regular watering; prune only lightly to remove crossing or dead branches; fertilize with balanced formula; deadhead spent flowers if desired

Harvest Tips
Cut fragrant flower stems in early morning when flowers are just opening for indoor arrangements and fragrance. Place cut stems in water immediately. Flowers last 1-2 weeks indoors. Avoid cutting more than one-third of the flowering wood in a season. Seeds are rarely harvested as the cultivar is typically propagated by cuttings.
Fun Facts
