The Story
Plant Bio
Ericameria nauseosa, the rubber rabbitbrush, is a deciduous, multi-stemmed shrub native to western North America that forms an upright, rounded framework of dense, brushy twigs covered in felt-like white to gray hairs. The narrow, linear leaves have a silvery-white to gray-green tomentose coating and release a strong, pungent odor when bruised.
During late summer and fall, the branch tips produce terminal, flat-topped clusters of small, bright yellow flower heads composed entirely of disc florets. These flowers provide a critical late-season food source for native bees, butterflies, and migrating hummingbirds in arid landscapes.

Planting
How to Grow
- Select a planting site in full sun with highly drained sandy, gravelly, or clay soil.
- Dig a hole twice the width of the root ball and set the plant at the same depth as its nursery container.
- Water deeply immediately after planting to settle the soil, then withhold water once the root system establishes.
- Avoid applying fertilizer or organic mulches, which trigger weak, floppy growth and promote root rot.
Pro Tip
Prune the stems lightly in late winter or early spring to maintain a dense shape, but never cut back into old, leafless wood as the plant cannot regenerate from bare branches.

Care Guide
Do
- Plant in poor, fast-draining soils to maintain a compact, upright habit.
- Prune lightly in late winter to prevent the shrub from becoming overly leggy.
- Allow the soil to dry out completely between waterings once established.
Don't
- Do not fertilize, as excess nutrients cause weak, floppy branches.
- Do not prune hard into old, bare wood, which kills the branches.
- Do not plant in wet, heavy soils or areas with standing water.

Common Questions
Rubber rabbitbrush questions
What zones can Rubber rabbitbrush grow in?
Rubber rabbitbrush is hardy in USDA Zones 4–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Rubber rabbitbrush deer resistant?
Not reliably. Deer may browse Rubber rabbitbrush, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Rubber rabbitbrush bloom?
Rubber rabbitbrush typically blooms in summer through autumn. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Rubber rabbitbrush need full sun?
Rubber rabbitbrush does best in full sun (6+ hours).
Is Rubber rabbitbrush drought tolerant?
Yes — once established (usually after the first full season), Rubber rabbitbrush handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
