Hairy False Ohelo: A Rare Hawaiian Native Worth Preserving
Meet the hairy false ohelo (Wikstroemia villosa), one of Hawaii’s most endangered native shrubs that deserves a place in every conservation-minded gardener’s heart. This unassuming little plant might not win any beauty contests, but its rarity and ecological importance make it a true treasure for those passionate about preserving Hawaii’s unique flora.
What Makes Hairy False Ohelo Special?
The hairy false ohelo is a perennial shrub that’s exclusively native to Hawaii, making it a genuine island endemic. This multi-stemmed woody plant typically stays compact, usually reaching less than 13 to 16 feet in height, though most specimens remain much smaller. Its botanical name, Wikstroemia villosa, hints at its villous or hairy nature, which gives the plant its common name.
You might also encounter this plant listed under its synonym, Wikstroemia caumii, in older botanical references.
Where Does It Grow?
This rare shrub calls Hawaii home and only Hawaii. It’s found across several Hawaiian islands, where it naturally grows in upland areas. The plant has a facultative upland wetland status, meaning it usually prefers non-wetland conditions but can occasionally tolerate wetter soils.
A Plant in Crisis
Here’s the sobering truth: hairy false ohelo is critically endangered. With a Global Conservation Status of S1 and listed as Endangered, this species is hanging by a thread. There are typically only five or fewer known occurrences, with fewer than 1,000 individuals remaining in the wild. This makes every single plant incredibly precious.
If you’re considering adding this species to your garden, it’s absolutely crucial that you source it responsibly. Never collect from wild populations, and only purchase from reputable native plant nurseries that propagate from legally obtained, ethically sourced material.

- Contributes to habitat restoration efforts
This shrub works best in specialized native gardens or as part of broader conservation landscaping efforts. Its modest size and unassuming appearance make it suitable for mixed native plantings where it won’t compete visually with more dramatic species.
Wildlife and Pollinator Benefits
While specific data on wildlife benefits is limited, native Hawaiian shrubs like hairy false ohelo typically support local ecosystems by providing habitat and food sources for native insects and birds. Every native plant helps maintain the delicate balance of Hawaii’s unique ecosystems.
Should You Grow Hairy False Ohelo?
The answer depends on your commitment to conservation and your location. If you’re in Hawaii or a similar tropical climate and passionate about preserving rare native species, this plant deserves consideration. However, remember that growing endangered species comes with responsibility.
Grow it if you:
- Live in an appropriate tropical climate (zones 10-12)

Consider alternatives if you:
- Live outside tropical zones
- Prefer showy, dramatic plants
- Can’t ensure responsible sourcing
