Establishment
6-8 weeksYoung transplants develop shallow root systems and minimal foliage growth
Water regularly (weekly) the first month to establish roots. Mulch lightly with gravel. Protect from extreme heat and wind in first season.
Vegetative Growth
3-4 monthsShrub develops branching structure and narrow, elongated gray-green foliage with aromatic compounds
Reduce watering frequency as plant matures. Light pruning in early spring encourages bushier form. No fertilizer needed; native plants thrive in poor soil.
Pre-flowering
4-6 weeksBranch tips begin to develop flower buds in late summer; foliage darkens slightly
Withhold supplemental water to encourage blooming. Prune any dead or crossing branches carefully to open canopy.
Flowering
6-8 weeks (August-October)Masses of small, bright golden-yellow flowers appear in dense clusters at branch tips; strong, pleasant camphor-like fragrance
Do not deadhead unless spent flowers bother you; allow flowers to remain for seed development and wildlife food. Continue dry conditions.
Seed Production & Dormancy
4-6 monthsFlowers fade to seed; plant gradually goes dormant. Foliage may redden slightly before dropping in colder zones
Allow seeds to mature and drop naturally for wildlife. Leave plant standing through winter for erosion control and shelter. Prune dead wood in spring after danger of frost passes.

Common Pests
-
Rare in established plants; mist foliage with water if infestation occurs. Strong air circulation prevents problems.
-
Usually not significant; native shrub is part of natural food chain. Netting seedlings only if severe.
-
Prevent by ensuring excellent drainage and avoiding overwatering. Remove affected plants entirely if rot develops.

Harvest Tips
Rabbit Brush is not harvested for food or typical garden products. However, branches and flowers can be cut for dried arrangements in late summer when flowers are fully open but before seeds drop. Cut stems 6-8 inches long and hang-dry in bunches in a cool, ventilated space for 2-3 weeks. Fresh flowers have a stronger fragrance than dried.
Fun Facts
