Rubber Rabbitbrush: A Native Gem for Western Gardens

Meet rubber rabbitbrush (Ericameria nauseosa nauseosa var. washoensis), a resilient native shrub that’s perfectly suited for water-wise gardens in California and Nevada. This hardy perennial offers year-round structure and seasonal interest, making it a valuable addition to native plant landscapes.

Where You’ll Find This Native Beauty

Rubber rabbitbrush is a true native of the American West, naturally occurring in California and Nevada. As a subspecies variety of the broader rabbitbrush family, this particular plant has adapted to the unique conditions of its limited range, making it especially well-suited for gardens in these regions.

What Makes Rubber Rabbitbrush Special

This multi-stemmed woody shrub typically stays manageable in size, usually growing less than 13 to 16 feet tall, though most garden specimens remain much smaller. Like other shrubs, it develops several stems from near the ground, creating a naturally full, rounded form that adds structure to your landscape year-round.

The plant goes by the scientific name Ericameria nauseosa nauseosa var. washoensis, though you might also see it referenced by its former botanical names in older gardening resources.

A Word About Conservation

Here’s something important to know: rubber rabbitbrush has a conservation status that suggests it may be somewhat uncommon in parts of its range. If you’re interested in growing this plant, make sure to source it responsibly from reputable native plant nurseries that propagate their own stock rather than wild-collecting.

Why Choose Rubber Rabbitbrush for Your Garden

Native plants like rubber rabbitbrush offer several advantages for gardeners:

  • Naturally adapted to local climate conditions
  • Typically requires less water once established
  • Supports local ecosystems and wildlife
  • Provides year-round garden structure
  • Low maintenance once established

Garden Design Ideas

Rubber rabbitbrush works beautifully in:

  • Native plant gardens
  • Water-wise landscapes
  • Wildlife habitat gardens
  • Mixed shrub borders
  • Naturalized areas

Growing Tips and Care

While specific growing information for this particular variety is limited, rabbitbrush species generally prefer:

  • Full sun locations
  • Well-draining soils
  • Minimal water once established
  • Good air circulation

As with most native shrubs, the key to success is mimicking the plant’s natural growing conditions. Since this species is native to California and Nevada, it’s likely adapted to dry summers and moderate winters typical of these regions.

Planning Your Purchase

When shopping for rubber rabbitbrush, look for nurseries that specialize in native plants and can guarantee their stock is nursery-propagated. Ask specifically about the variety name to ensure you’re getting the true Ericameria nauseosa nauseosa var. washoensis rather than a closely related species.
