Sticky Sprangletop: A Specialized Native Grass for the Southwest
If you’re passionate about native plants and love discovering the more unusual members of your local flora, you might want to learn about sticky sprangletop (Leptochloa viscida). This annual grass is one of those fascinating native species that flies under the radar of most gardeners, but deserves a closer look for its ecological value and unique southwestern heritage.
What is Sticky Sprangletop?
Sticky sprangletop is a native annual grass that belongs to the graminoid family – that diverse group of grass-like plants that includes true grasses, sedges, and rushes. You might also see it listed under its synonyms Dinebra viscida or Diplachne viscida in older botanical references. As its common name suggests, this grass has a somewhat sticky quality that sets it apart from other native grasses in its range.
Where Does It Grow?
This native beauty calls the American Southwest home, naturally occurring in Arizona, California, New Mexico, and Texas. It’s perfectly adapted to the unique growing conditions of these regions, having evolved alongside the other native plants and wildlife of the southwestern United States.

A Word of Caution: Rarity Matters
Before you get too excited about adding sticky sprangletop to your garden, there’s something important to consider. This grass has a Global Conservation Status of S3S4, which indicates it may have some conservation concerns. If you’re interested in growing this species, it’s crucial to source it responsibly from reputable native plant nurseries or seed suppliers who can verify that their stock doesn’t impact wild populations.
Growing Conditions and Habitat Preferences
Sticky sprangletop shows interesting flexibility when it comes to moisture conditions, which tells us a lot about where it might fit in your landscape:
- In the Arid West, it typically grows in non-wetland areas but can tolerate some moisture
- In the Great Plains region, it similarly prefers drier sites but adapts to occasional wetness
- In the Western Mountains, Valleys, and Coast region, it actually prefers wetland conditions but can handle drier spots
This adaptability suggests that sticky sprangletop could work in various garden situations, from rain gardens to more traditional xeriscaping, depending on your specific location and microclimate.
Should You Grow Sticky Sprangletop?
As an annual grass, sticky sprangletop completes its entire life cycle in one growing season, which means it will need to reseed itself or be replanted each year. This characteristic makes it more challenging for the average gardener compared to perennial native grasses that return year after year.
Consider sticky sprangletop if you:
- Are passionate about supporting local native plant biodiversity
- Have experience with annual plants and don’t mind reseeding
- Want to create habitat that closely mimics natural southwestern ecosystems
- Are working on a restoration project in its native range
However, you might want to choose other options if you’re looking for low-maintenance perennial grasses or don’t have access to responsibly sourced seeds or plants.
The Bottom Line
Sticky sprangletop is one of those native plants that appeals most to dedicated native plant enthusiasts and restoration practitioners rather than general gardeners. Its annual nature, limited availability, and conservation status make it a specialized choice. If you’re drawn to this unique southwestern native, make sure to source it responsibly and consider it as part of a broader commitment to supporting native plant communities in your region.
For most gardeners interested in native southwestern grasses, you might want to start with more readily available perennial native options and work your way up to specialized species like sticky sprangletop as your native gardening skills develop.
