Planting and Care Tips

Since this is a hardy native, your main job is simply not to love it to death with too much water or rich soil. Plant in spring or fall, give it space to spread, and then step back and let it do its thing. The most common mistake gardeners make is overwatering – remember, this plant evolved in arid conditions and prefers the tough love approach.

Supporting Pollinators and Wildlife

While specific wildlife benefit data for this variety isn’t readily available, rubber rabbitbrush varieties are generally excellent for supporting native pollinators, especially late in the season when other blooms are scarce. This makes it a valuable addition to any wildlife-friendly garden.

The Bottom Line

Rubber rabbitbrush isn’t for every garden or every gardener, but if you’re looking for an authentic native plant that can handle tough conditions while supporting local wildlife, it’s definitely worth considering. Just make sure you have the space for it to express its natural character, and you’ll be rewarded with a truly resilient and ecologically valuable addition to your landscape.

Before planting, try to source your plants from reputable native plant nurseries to ensure you’re getting healthy, locally appropriate stock. Your local extension office or native plant society can often provide recommendations for the best sources in your area.
