Establishment
2-3 monthsYoung transplants are small and focus on root development
Water moderately during first 2-3 months to establish roots; then reduce watering. Plant in spring for best establishment. Avoid heavy organic mulch that retains moisture.
Vegetative Growth
Spring through early summer (first year)Shrub develops compact mounding form with fine-textured gray-green foliage; no flowers yet
Minimal pruning needed. Light pruning after flowering encourages bushiness. No fertilizer needed; poor soil actually encourages better form.
Flowering
6-8 weeks (May-July in Northern Hemisphere)Profuse magenta-pink flowers with dark burgundy blotches appear at branch tips; each bloom lasts one day but continuous succession of new flowers
Peak bloom in late spring through early summer. Deadheading not necessary as flowers drop naturally. Ensure full sun for maximum flowering. No supplemental watering during bloom.
Summer Dormancy
2-3 months (July-September)Flowering slows or stops in peak heat; plant may look sparse but remains evergreen
Do not water or fertilize. This is normal behavior. Maintain full sun exposure. Plant is conserving energy in extreme heat.
Mature Shrub
Year 2 onwardEstablished plant maintains compact, mounding form 3-4 feet tall and wide with gray-green evergreen foliage
Minimal maintenance. Drought-tolerant. Occasional light pruning to maintain shape. No pest or disease issues in proper conditions. Very long-lived plant (20+ years).

Fun Facts
- 🌱 Cistus × purpureus is a hybrid between Cistus ladanifer and Cistus villosus, combining the best traits of both parents for ornamental purposes.
- 🌱 The papery flowers last only a single day, but a healthy plant produces hundreds of blooms over 6-8 weeks in succession, creating continuous color throughout late spring and early summer.
- 🌱 In Mediterranean regions, Cistus plants produce a fragrant resinous substance called 'labdanum' that has been collected and used in perfumery and incense for thousands of years, though C. purpureus produces less than some species.
