If you’re passionate about native California plants and love supporting rare species, Clokey’s nightshade might just be the perfect addition to your garden. This charming perennial herb, scientifically known as Solanum clokeyi, is a true California treasure that deserves a spot in the right garden setting.

What Makes Clokey’s Nightshade Special

Clokey’s nightshade is a native California perennial that belongs to the nightshade family. As a forb herb, it’s a non-woody plant that dies back to the ground each winter and returns faithfully each spring. Don’t let its delicate appearance fool you – this tough little plant has adapted to some pretty challenging conditions in its native habitat.

You might also see this plant listed under its former scientific names, including Solanum wallacei var. clokeyi or Solanum wallacei ssp. clokeyi, but Solanum clokeyi is the currently accepted name.

Where Does It Call Home?

This native beauty is found exclusively in California, making it a true endemic species. It has carved out its niche in the Golden State’s diverse landscapes, particularly thriving in rocky, well-draining areas.

A Plant That Needs Our Help

Here’s something important to know: Clokey’s nightshade has a Global Conservation Status of S3, meaning it’s considered vulnerable. With typically only 21 to 100 occurrences and between 3,000 to 10,000 individuals in the wild, this plant is quite rare. If you’re considering adding it to your garden, please make sure you source it responsibly from reputable native plant nurseries that propagate their own stock rather than collecting from wild populations.

Garden Appeal and Design Uses

While Clokey’s nightshade might not be the showiest plant in your garden, it brings a subtle charm that native plant enthusiasts absolutely love. Its small purple flowers are typical of the nightshade family and provide delicate color during its blooming season. The plant’s low-growing, herbaceous nature makes it perfect for:

  • Rock gardens and xeriscaped areas
  • Native plant collections
  • Naturalistic landscapes that mimic California’s wild spaces
  • Educational gardens focused on rare or endemic species

Supporting Local Wildlife

As with many native plants, Clokey’s nightshade likely provides benefits to local wildlife, particularly native pollinators. The flowers attract small bees and other beneficial insects, making it a valuable addition to pollinator-friendly gardens. By choosing native plants like this one, you’re helping support the intricate web of relationships between plants and animals that have evolved together over thousands of years.

Growing Conditions and Care

Clokey’s nightshade is adapted to California’s Mediterranean climate and typically thrives in USDA hardiness zones 8-10. Here’s what this rare beauty needs to flourish:

  • Sunlight: Full sun to partial shade
  • Soil: Well-draining soil is absolutely essential – this plant hates wet feet
  • Water: Drought tolerant once established, requiring minimal supplemental watering
  • Soil type: Prefers rocky, sandy, or gravelly soils that drain quickly

Planting and Care Tips

If you’re lucky enough to find Clokey’s nightshade at a reputable native plant nursery, here are some tips for success:

  • Plant in fall or early spring when temperatures are mild
  • Ensure excellent drainage – consider planting on a slope or in a raised bed if your soil tends to stay wet
  • Water regularly the first year to help establish roots, then reduce watering significantly
  • Avoid fertilizers, which can actually harm many California natives
  • Allow the plant to go dormant in winter – don’t be alarmed when it dies back to the ground
  • Mulch lightly with gravel or decomposed granite rather than organic mulch

Is Clokey’s Nightshade Right for Your Garden?

This plant is definitely for the dedicated native plant gardener rather than someone looking for bold, showy flowers or fast-growing groundcover. Consider Clokey’s nightshade if you:

  • Are passionate about California native plants
  • Want to support rare and vulnerable species
  • Have well-draining soil or are willing to create it
  • Appreciate subtle beauty over flashy displays
  • Are committed to responsible gardening practices

Remember, because this plant is rare in the wild, only purchase from nurseries that clearly state they propagate their own plants. By growing Clokey’s nightshade responsibly, you’re not just adding a unique California native to your garden – you’re also participating in the conservation of a vulnerable species. Now that’s something to feel good about!
