Establishment (Spring)
4-6 weeksNewly planted shrub develops roots and produces fresh green shoots from the base and branches.
Water regularly to establish deep root system. Apply 2-3 inches of mulch around base, keeping away from stems. Prune back by 1/3 in early spring to encourage bushier growth.
Vegetative Growth (Late Spring-Early Summer)
6-8 weeksPlant develops dense foliage with silvery-green, finely textured leaves. Stems elongate and branch prolifically.
Maintain consistent but not excessive moisture. Deadhead any early flower buds to redirect energy into foliage. Light feeding with balanced fertilizer mid-spring.
Flowering (Mid-Summer-Fall)
12-16 weeksAbundant spikes of small blue-purple, fragrant flowers appear at branch tips. Blooms progress from bottom to top of inflorescence.
Deadhead spent flowers regularly to encourage continuous blooming through frost. Water moderately; don't overwater as this reduces flower intensity. No fertilizer needed once blooming begins.
Senescence (Fall-Winter)
8-12 weeksFoliage may yellow and drop in colder zones (deciduous); in milder zones remains semi-evergreen. Plant hardens off for dormancy.
Reduce watering significantly. In zones 5-6, prune back hard (to 6-12 inches) in late fall or early spring before growth resumes. In zones 8-9, minimal pruning needed.
Dormancy-Regrowth (Winter-Early Spring)
8-16 weeksPlant is dormant or semi-dormant; little visible growth above ground, but root activity continues in milder zones.
No watering needed in most regions. Protect with mulch in zone 5. Check for winter damage and remove dead wood in spring.

Fun Facts

- 🌱 The foliage is aromatic and contains volatile oils with a distinctive spicy-mint scent; crushing a leaf releases an intensified fragrance that can repel some insects.
- 🌱 Caryopteris First Choice is a relatively modern cultivar selected for its improved compact habit (typically 24-30 inches tall and wide) compared to species plants, making it more suitable for small gardens and containers.
