Jones Spiderflower: A Rare Desert Gem Worth Protecting

If you’re drawn to unique desert wildflowers and have a passion for conservation gardening, you might be intrigued by Jones spiderflower (Cleome lutea var. jonesii). This distinctive annual belongs to the spiderflower family and represents a fascinating piece of Arizona’s botanical heritage that deserves our attention and protection.

What Makes Jones Spiderflower Special

Jones spiderflower is a native annual forb, meaning it’s a non-woody plant that completes its entire life cycle in one growing season. As a member of the Cleome family, it likely shares the characteristic spider-like flower structure that gives spiderflowers their memorable name, though specific details about this variety’s appearance are limited in available research.

This plant goes by several scientific names, including Cleome jonesii and Peritoma jonesii, reflecting the ongoing botanical classification work that helps us better understand plant relationships.

A True Arizona Native

Jones spiderflower is exclusively native to Arizona, making it a true regional specialty. This limited geographic distribution contributes to its conservation concerns and makes it particularly valuable for authentic desert landscaping projects.

Important Conservation Considerations

Here’s where things get serious: Jones spiderflower has a Global Conservation Status of S5T1T3, indicating it’s quite rare. If you’re considering adding this plant to your garden, it’s crucial to source it responsibly. Never collect seeds or plants from wild populations, as this can harm already vulnerable communities.

Instead, look for:

  • Seeds from reputable native plant societies
  • Plants from nurseries that specialize in rare native species
  • Seed swaps with other conservation-minded gardeners
  • Participation in conservation seed collection programs

Growing Conditions and Habitat

Based on its wetland status classification as Facultative Upland in both the Arid West and Western Mountains regions, Jones spiderflower typically thrives in non-wetland conditions but can tolerate occasional moisture. This suggests it’s adapted to Arizona’s variable desert conditions where rainfall is sporadic but sometimes abundant.

As an annual forb native to Arizona’s desert regions, it likely prefers:

  • Well-draining, rocky or sandy soils
  • Full sun exposure
  • Minimal summer irrigation
  • Natural winter-spring rainfall patterns

Should You Grow Jones Spiderflower?

The answer depends on your gardening goals and commitment level. This isn’t a plant for casual gardeners or those looking for reliable, showy displays. However, it might be perfect for you if:

  • You’re passionate about conservation and rare plant preservation
  • You’re creating an authentic Arizona desert landscape
  • You enjoy the challenge of growing uncommon species
  • You want to contribute to maintaining genetic diversity in cultivation

Keep in mind that as an annual, Jones spiderflower will need to reseed each year to maintain its presence in your garden. Success may be variable, and patience will definitely be required.

The Bigger Picture

Growing rare native plants like Jones spiderflower is about more than just adding novelty to your garden. It’s about participating in conservation efforts, preserving genetic diversity, and maintaining connections to regional plant communities that have evolved over thousands of years.

While we may not have all the specific growing details for this particular variety, your experimentation and observations could contribute valuable knowledge to the gardening and conservation communities. Consider documenting your experiences and sharing them with local native plant societies.

Whether or not you decide to take on the challenge of growing Jones spiderflower, its story reminds us of the incredible diversity hidden within our native flora and the importance of protecting these botanical treasures for future generations.

Cleome lutea var. jonesii is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Cleome lutea var. jonesii is also known as:

Cleome jonesii | USDA symbol: CLJO
Peritoma jonesii | USDA symbol: PEJO

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
