Ridgetop Bloodgrass: A Rare Hawaiian Native Worth Protecting in Your Garden
If you’re passionate about native Hawaiian plants and want to support conservation efforts right in your backyard, ridgetop bloodgrass (Isachne distichophylla) might just be the perfect addition to your landscape. This perennial grass, also known simply as ‘ohe in Hawaiian, represents something truly special – a vulnerable piece of Hawaii’s natural heritage that deserves our attention and care.
What Makes Ridgetop Bloodgrass Special?
Ridgetop bloodgrass is a native Hawaiian perennial grass that belongs to the diverse grass family (Poaceae). As a true endemic species, it evolved specifically in the Hawaiian Islands and exists nowhere else on Earth. This grass-like plant has adapted to Hawaii’s unique climate and growing conditions over thousands of years, making it perfectly suited to island life.
Where Does It Grow?
This remarkable grass calls Hawaii home exclusively. You won’t find ridgetop bloodgrass growing wild anywhere else in the world – it’s found only throughout the Hawaiian Islands, making it a true treasure of the Pacific.
A Plant That Needs Our Help
Here’s something important every gardener should know: ridgetop bloodgrass has a Global Conservation Status of S3, meaning it’s considered vulnerable. With typically only 21 to 100 occurrences or between 3,000 and 10,000 individuals remaining, this species is either very rare and local throughout its range or faces other factors that make it vulnerable to disappearing entirely.
What this means for you: If you choose to grow ridgetop bloodgrass, please make sure you source it responsibly from reputable native plant nurseries or conservation organizations. Never collect plants from the wild – this could further threaten already vulnerable populations.
Growing Ridgetop Bloodgrass: The Basics
While detailed cultivation information for this rare grass is limited, we do know some key facts that can guide your growing efforts:
Moisture Preferences
Ridgetop bloodgrass has a facultative wetland status in Hawaii, which means it’s quite adaptable when it comes to water. This flexible plant can thrive in both wetland and non-wetland conditions, making it potentially suitable for various garden situations – from rain gardens to drier landscape areas.
What We’re Still Learning
Unfortunately, specific details about this grass’s preferred growing conditions, propagation methods, mature size, and care requirements aren’t well-documented in horticultural literature. This is common with rare native species that haven’t been widely cultivated.
