Important Conservation Note
Before you rush out to plant rubber rabbitbrush, there’s something important to know: this variety has a conservation status that suggests it may be somewhat rare or vulnerable in the wild. If you decide to grow it, please make sure you’re purchasing from reputable nurseries that grow their plants from ethically collected seed or cuttings, rather than wild-harvesting. This helps protect wild populations while still allowing you to enjoy this beautiful native in your garden.
Growing Rubber Rabbitbrush Successfully
The good news is that rubber rabbitbrush is relatively easy to grow once you understand its preferences:
Ideal Growing Conditions
- Sunlight: Full sun is essential for best flowering and growth

- Water: Drought tolerant once established, but benefits from occasional deep watering during extreme dry spells
- Climate: Thrives in USDA hardiness zones 8-10
Planting and Care Tips
Getting your rubber rabbitbrush off to a good start is pretty straightforward:
- Plant in fall or early spring when temperatures are moderate
- Dig a hole twice as wide as the root ball but no deeper
- Water regularly the first year to help establish roots, then reduce watering
- Prune lightly after flowering to maintain shape and encourage bushier growth
- Avoid overwatering or overfertilizing – this plant prefers lean conditions
