Establishment
First 6-12 monthsYoung plant with limited growth, small shoots and leaves
Water regularly, avoid heavy fertilizing; stake or tie loosely to support structure. Apply 2-3 inches of mulch around base.
Vegetative Growth
Year 2, spring through early summerVigorous cane development with long, flexible stems and glossy foliage
Train canes horizontally along support to encourage branching and flowering. Fertilize monthly during growing season with rose fertilizer. Remove diseased or crossing canes.
Flowering
Late spring through summer (5-8 weeks typically)Abundant clusters of small, single pink flowers with white centers bloom prolifically along canes
Deadhead spent flowers to encourage more bloom; however, leave some to develop hips. Water consistently. Monitor for powdery mildew in humid conditions.
Hip Development
Late summer through fall/winterAfter flowering, red ornamental hips form and persist through fall
Leave hips on plant for wildlife food and autumn interest. Reduce watering slightly. Continue monitoring for pests.
Dormancy
Winter monthsFoliage drops; bare canes remain on support structure
Prune in late winter (late February-March in cold climates) to remove dead wood and shape plant. Cut out one-third of oldest canes at base to rejuvenate. Apply dormant oil spray if pest issues occurred.

Uses
Floral arrangements and cutting
CraftThe flowers are excellent for fresh arrangements, especially when combined with foliage that provides color and texture. The cut flowers have a light fragrance and hold reasonably well in water. [source]
Bird and pollinator food source
WildlifeThe fragrant flowers attract bees, butterflies, and other pollinators during blooming season. The ornamental red hips provide valuable food for birds, especially robins and cedar waxwings, well into winter. [source]
Garden structure coverage and ornament
HouseholdAmerican Pillar rapidly covers fences, trellises, arbors, and pergolas with lush green foliage and spectacular flower displays. Its vigorous, flexible canes make it ideal for training over tall structures. [source]
Herbal tea from hips
CulinaryRose hips are rich in vitamin C and can be harvested in fall to make herbal tea, jams, or syrups. The tart-sweet flavor is invigorating and the hips have been used traditionally for immune support. [source]
Traditional herbal remedy
MedicinalHistorically, rose hips have been used in traditional medicine for their high vitamin C content and potential anti-inflammatory properties. Modern herbalists use dried hips for teas and tinctures. [source]

Harvest Tips
Cut flowers in early morning when stems are hydrated; use sharp scissors and take long stems with several leaves. Cut at 45-degree angle above outward-facing bud. For decorative hips, allow flowers to fade naturally and harvest in fall when fully red. Leave some hips on plant for birds.
