Slender Spiderflower: A Delicate Native Annual for Water-Wise Gardens
If you’re looking for a charming native wildflower that won’t demand much from your garden but gives back plenty in return, meet the slender spiderflower (Cleome multicaulis). This delicate annual might not be the showiest flower in your garden, but it’s got a quiet elegance that makes it a perfect addition to naturalistic landscapes and water-wise gardens.
What Is Slender Spiderflower?
Slender spiderflower is a native annual forb that belongs to the cleome family. Unlike its more flamboyant garden cousins, this little wildflower keeps things subtle with small clusters of white to pale pink flowers that dance on slender stems. As an herbaceous plant, it lacks woody tissue and completes its entire life cycle in one growing season, making it a true annual.
You might also see this plant listed under its synonyms Cleome sonorae or Peritoma multicaulis in some references, but they’re all the same delightful little flower.
Where Does It Call Home?
This native beauty calls the American Southwest home, naturally occurring across Arizona, Colorado, New Mexico, Texas, and Wyoming. It’s perfectly adapted to the semi-arid and desert regions of these states, thriving in conditions that would leave many garden plants wilting.
Important Conservation Note
Before you get too excited about adding slender spiderflower to your garden, there’s something important to know: this plant has a Global Conservation Status of S2S3, which indicates it may be somewhat rare or uncommon in parts of its range. This doesn’t mean you shouldn’t grow it – quite the opposite! – but it does mean you should source your seeds or plants responsibly from reputable native plant suppliers who collect sustainably or grow from cultivated stock.

Wildlife and Pollinator Benefits
