Mokulei Rosemallow: Hawaii’s Rare Native Treasure Worth Protecting
If you’re passionate about Hawaiian native plants and conservation gardening, the Mokulei rosemallow (Hibiscus brackenridgei mokuleianus) deserves a spot on your must-know list. This isn’t just any hibiscus – it’s a critically rare subspecies of Hawaii’s official state flower, and growing it responsibly can make you part of an important conservation effort.
What Makes Mokulei Rosemallow Special?
The Mokulei rosemallow is a perennial shrub that’s endemic to Hawaii, meaning you won’t find it growing naturally anywhere else on Earth. As a member of the hibiscus family, it shares the classic beautiful yellow blooms that Hawaii’s state flower is famous for, but this particular variety has its own unique characteristics that make it stand out from its more common relatives.
This multi-stemmed woody plant typically grows as a shrub, usually staying under 13-16 feet tall, though it can sometimes grow taller or develop a single stem depending on environmental conditions. What makes it truly special isn’t just its beauty – it’s its incredible rarity.
A Plant on the Edge: Understanding Its Rarity
Important Conservation Note: The Mokulei rosemallow has a Global Conservation Status of S1T1, which means it’s critically imperiled. This isn’t a plant you’ll find at your local garden center, and that’s exactly why it needs our attention.
If you’re considering adding this plant to your garden, it’s crucial to source it responsibly. Only work with reputable native plant nurseries or conservation organizations that can provide ethically propagated specimens. Never collect plants from the wild – this could further threaten the species’ survival.
Where Does It Call Home?
This remarkable plant is found exclusively in Hawaii, where it grows as part of the islands’ unique native ecosystem. Its limited geographic distribution is part of what makes it so vulnerable and so precious to Hawaii’s natural heritage.

- Conservation Impact: By growing responsibly sourced plants, you’re helping preserve genetic diversity and supporting conservation efforts
- Cultural Significance: You’re cultivating a piece of Hawaiian heritage and helping maintain the connection to the islands’ state flower
