Establishment
3-4 monthsYoung shrub with delicate silvery foliage establishing root system and initial branch structure
Water regularly for first 2-3 months; avoid fertilizing first season to allow root development
Vegetative Growth
4-6 monthsRapid foliage development with characteristic silvery-purple leaves emerging throughout spring and early summer
Allow natural form to develop; minimal pruning needed; apply balanced fertilizer in early spring
Flowering
3-4 weeksSmall (1-1.5 inch) single pink flowers with pale centers bloom profusely along branches in late spring
Deadheading is optional as hips are ornamental; maintain consistent moisture during bloom period
Hip Formation & Maturation
3-4 monthsFlowers fade and transform into bright red ornamental hips that persist through fall and winter
Do not deadhead if hips are desired; hips provide food for wildlife; reduce watering slightly in fall
Dormancy
3-4 monthsFoliage remains silvery but may take on deeper purple tones; branches become woody and visible; hips persist
Minimal watering; prune in late winter to remove dead wood and shape if needed; excellent winter structure
