Rush Broom: A California Native with Mysterious Charm

If you’re looking to add a touch of California’s natural heritage to your garden, rush broom (Lotus junceus) might just be the understated native you’ve been searching for. This perennial herb brings a bit of botanical mystery to the table – and sometimes that’s exactly what makes a plant intriguing!

What Is Rush Broom?

Rush broom is a native perennial forb that calls California home. As a member of the legume family, this herbaceous plant lacks the woody stems you’d find on shrubs or trees. Instead, it maintains its perennial nature through underground structures that help it return year after year, making it a reliable addition to native plant gardens.

The plant’s scientific classification as a forb means it’s essentially a soft-stemmed flowering plant – think of it as the botanical equivalent of a gentle, non-woody wildflower that’s perfectly adapted to California’s unique climate and growing conditions.

Where Does Rush Broom Grow?

This California native has made the Golden State its exclusive home within the lower 48 states. While many native plants have sprawling ranges across multiple states, rush broom has chosen to be a California specialist, focusing its energy on thriving in the diverse habitats that the state has to offer.

Why Consider Rush Broom for Your Garden?

Choosing native plants like rush broom offers several compelling benefits:

  • True California heritage: You’re literally planting a piece of California’s natural history
  • Low-maintenance perennial: Once established, native perennials typically require less water and care than non-native alternatives
  • Ecological authenticity: Native plants support local ecosystems in ways that non-natives simply cannot match
  • Climate adaptation: Already perfectly suited to California’s weather patterns and soil conditions

The Challenge with Rush Broom

Here’s where rush broom becomes particularly intriguing – and admittedly challenging. This native appears to be either quite rare in cultivation or possibly exists under different common names in the nursery trade. While this adds to its mystique, it also means that finding reliable growing information and plant sources can be tricky.

If you’re determined to grow rush broom, you’ll likely need to:

  • Contact specialized native plant nurseries in California
  • Reach out to local native plant societies for guidance
  • Consider participating in seed collection efforts (with proper permissions)
  • Connect with botanical gardens that focus on California natives

  • Deerweed (Acmispon glaber): A widespread California native with similar growth habits
  • Silver lupine (Lupinus albifrons): Another beautiful native legume with striking flowers
  • California broom (Pickeringia montana): A woody native that shares the broom common name

The Bottom Line

Rush broom represents one of those fascinating native plants that reminds us how much we still have to learn about our local flora. While it may not be the easiest native to source or grow, its authentic California heritage makes it worth considering for dedicated native plant enthusiasts.

If you do manage to locate rush broom for your garden, you’ll be growing a true piece of California’s botanical heritage – and likely learning something new about native plant cultivation in the process. Sometimes the most rewarding garden plants are the ones that challenge us to dig a little deeper into the natural world around us.
