Sticky Monkeyflower: A Rare California Native Worth Knowing

Meet the sticky monkeyflower (Mimulus viscidus viscidus), a charming little California native that’s definitely flying under the radar in most gardening circles. This annual wildflower belongs to the diverse monkeyflower family, and while it might not be the showiest plant in your garden, it carries the special distinction of being a true Golden State original.

What Makes This Plant Special?

The sticky monkeyflower is what botanists call a forb – basically a soft-stemmed, herbaceous plant that completes its entire life cycle in just one growing season. As an annual, it germinates, grows, flowers, sets seed, and dies all within a single year, making it quite different from the perennial plants many gardeners are used to working with.

You might also encounter this plant listed under its scientific synonyms, including Mimulus fremontii var. viscidus or Mimulus subsecundus var. viscidus, which can make tracking down information about it a bit of a treasure hunt!

Where Does It Call Home?

This native beauty is exclusively a Californian, naturally occurring only within the diverse ecosystems of the Golden State. As a plant that evolved specifically in California’s unique climate and soil conditions, it represents an authentic piece of the region’s botanical heritage.

A Word About Rarity

Here’s something important to know: the sticky monkeyflower carries a Global Conservation Status of S4T3T4, which indicates it’s considered somewhat rare or uncommon. This rarity status means that if you’re interested in growing this plant, you’ll want to be extra thoughtful about where you source your seeds or plants.

Always look for:

  • Reputable native plant nurseries that ethically propagate their stock
  • Seeds collected from cultivated plants, not wild populations
  • Suppliers who can verify their plants weren’t collected from natural habitats

Should You Grow It?

The sticky monkeyflower presents an interesting case for native plant enthusiasts. On one hand, it’s a legitimate California native that could contribute to regional biodiversity in your garden. On the other hand, its rarity means we need to be responsible stewards.

If you’re drawn to supporting rare native plants and can source responsibly propagated material, this could be a meaningful addition to a native plant collection. However, detailed growing information for this specific variety is quite limited, which might make it challenging for beginning native gardeners.

Growing Considerations

Unfortunately, specific cultivation information for Mimulus viscidus viscidus is scarce, which reflects both its rarity and its limited presence in the horticultural trade. As an annual California native, it would likely prefer conditions similar to other members of the monkeyflower family, but without detailed growing guides, cultivating this plant would be somewhat experimental.

Given the information gaps and rarity status, beginning gardeners might want to start with better-documented California native annuals before tackling this particular species.

The Bottom Line

The sticky monkeyflower represents the fascinating diversity of California’s native flora, but it’s not your everyday garden plant. If you’re an experienced native plant gardener looking for a conservation challenge and can source plants responsibly, it might be worth exploring. For most gardeners, though, there are plenty of other California native annuals that are both easier to grow and more readily available.

Remember, supporting native plants doesn’t always mean growing the rarest ones – sometimes the best way to help preserve biodiversity is by creating habitat with more common native species while leaving the rare ones to specialized conservation efforts.
