Establishment
3-6 monthsYoung transplants develop root system and initial stem growth. Plant is small and relatively sparse.
Water consistently, mulch around base, avoid pruning first year to allow energy for root development. Protect from extreme cold in first winter.
Vegetative Growth
6-18 monthsPlant spreads horizontally, developing long trailing canes with glossy dark green foliage. Dense mounding habit begins to establish.
Continue regular watering. Minimal pruning needed; selectively remove dead or diseased wood. Allow natural spreading growth habit.
Flowering
4-8 weeks (spring and/or summer)Small fragrant flowers (0.75-1.5 inches) appear in clusters along trailing stems. Blooms are typically white or light pink and sweetly scented.
Flowers appear once or twice per season depending on climate. Deadheading not necessary but can encourage repeat blooming. Continue regular watering during flowering.
Fruiting & Dormancy
4-6 monthsSmall red hips (seed pods) develop after flowering. Foliage may persist year-round in warmer zones; deciduous in colder regions. Plant goes dormant in winter.
Leave hips on plant for wildlife food and ornamental interest. Minimal winter care needed except in extreme cold zones; mulch if temperatures drop below -15°F. Prune in early spring before new growth.
Full Maturity
Ongoing, typically 20+ yearsPlant has spread to create a dense, 2-3 foot tall ground cover with extensive trailing stems covering 4-8 feet or more. Established root system is very hardy.
Minimal maintenance required. Occasional pruning to maintain desired shape and remove dead wood. Very drought-tolerant once fully established.
