Minimal fertilizer needed; light pruning encourages bushier growth. Ensure excellent drainage to prevent fungal issues.
Flowering

Deadheading spent flowers extends blooming period. Reduce watering slightly during peak flowering. No fertilizer needed.
Seed Development
4-6 weeksFlowers fade and are replaced by small seed capsules that dry on the plant
Allow some flowers to remain for seed formation if desired. Collect seeds once capsules brown and split.
Dormancy/Winter Rest
2-4 months depending on locationGrowth slows; plant retains evergreen foliage but flowering ceases in cool climates
Minimize watering. In zones 8-9, provide frost cloth or wall protection during hard freezes. No fertilizing needed.

- 🌱 The resin from cistus species, called labdanum, has been used since ancient times in perfumery and was even used to embalm mummies in ancient Egypt.
- 🌱 Cistus is extremely fire-adapted; many Mediterranean species have seeds that germinate in response to heat from wildfires, making them pioneer plants in fire-adapted ecosystems.
