Doubleclaw: A Quirky Native Annual for Southwestern Gardens

Meet doubleclaw (Proboscidea parviflora parviflora var. parviflora), one of nature’s more unusual native plants that’s sure to spark conversation in any garden. This distinctive annual forb brings a touch of the wild Southwest to your landscape, complete with fascinating seed pods that give the plant its memorable common name.

What Makes Doubleclaw Special

Doubleclaw belongs to a unique family of plants known for their extraordinary seed pods. As an annual forb, this native plant completes its entire life cycle in just one growing season, making it a perfect choice for gardeners who enjoy watching dramatic seasonal changes in their landscape.

Unlike woody shrubs or trees, doubleclaw is a soft-stemmed plant that grows from the ground up each year. This growth habit makes it incredibly adaptable and allows it to fill different roles in your garden design depending on where and how you plant it.

Where Doubleclaw Calls Home

This remarkable native plant has made itself at home across six southwestern states: Arizona, California, Nevada, New Mexico, Texas, and Utah. Its natural range tells us a lot about what this plant needs to thrive – it’s perfectly adapted to the challenging conditions of the American Southwest.

Why Consider Doubleclaw for Your Garden

Choosing native plants like doubleclaw offers several advantages for both you and local wildlife:

  • Perfect adaptation to local climate conditions means less maintenance once established
  • Supports local ecosystems by providing habitat and food sources native wildlife have evolved with
  • Requires less water and fertilizer compared to non-native alternatives
  • Adds authentic regional character to your landscape design
  • Creates opportunities for education and conversation about native plant communities

Garden Design Possibilities

As an annual forb, doubleclaw works wonderfully in several garden settings:

  • Native plant gardens that celebrate regional flora
  • Xeriscaped landscapes designed for water conservation
  • Wildlife gardens focused on supporting local ecosystems
  • Educational gardens where the unusual seed pods can serve as conversation starters
  • Mixed borders where its annual nature allows for seasonal variety

Growing Doubleclaw Successfully

Since specific growing condition information isn’t readily available for this particular variety, it’s best to mimic the natural conditions where doubleclaw thrives in the wild. Based on its native range across the Southwest, this plant likely prefers:

  • Well-draining soils that don’t stay wet for extended periods
  • Full sun to partial sun exposure
  • Hot, dry summers typical of its native region
  • Minimal supplemental watering once established
  • USDA hardiness zones that correspond to its native range (likely zones 7-10)

Planting and Care Tips

As an annual, doubleclaw will need to be replanted each growing season, either from seed or transplants. Here are some general guidelines:

  • Plant after the last frost date in your area
  • Choose a location with good drainage to prevent root rot
  • Allow adequate spacing for the plant to reach its full size
  • Water regularly during establishment, then reduce as the plant matures
  • Collect seeds from mature pods if you want to grow it again next year

Is Doubleclaw Right for Your Garden?

Doubleclaw is an excellent choice if you’re gardening within its native range and want to create a landscape that reflects your local ecosystem. Its annual nature means you can experiment with it without making a long-term commitment, and its unique characteristics make it a fascinating addition to native plant collections.

However, if you’re looking for a plant that provides consistent structure year after year, you might want to pair doubleclaw with perennial native companions that will return each season.

Whether you’re a seasoned native plant enthusiast or just beginning to explore regional flora, doubleclaw offers a wonderful opportunity to connect with the wild character of the American Southwest right in your own backyard.
