Waianae Range Starviolet: A Critically Rare Hawaiian Treasure

Meet the Waianae Range starviolet (Hedyotis degeneri var. coprosmifolia), a plant so rare that most gardeners will never encounter it – and perhaps that’s for the best. This perennial shrub represents one of Hawaii’s most critically endangered native plants, making it more of a conservation priority than a garden addition.

What Makes This Plant Special

The Waianae Range starviolet belongs to the coffee family and grows as a multi-stemmed woody shrub, typically reaching less than 13-16 feet in height. Like many Hawaiian natives, it has evolved in isolation, developing unique characteristics that make it perfectly adapted to its specific island environment.

Where You’ll Find It (Or Won’t)

This remarkable plant calls Hawaii home – specifically, it’s believed to be endemic to the Waianae Range on Oahu. Its geographic distribution is extremely limited, which contributes significantly to its precarious conservation status.

The Rarity Reality Check

Here’s where things get serious: the Waianae Range starviolet has a Global Conservation Status of S1T1, which indicates it’s critically imperiled. In plain English? This plant is hanging on by a thread in the wild, with very few populations remaining.

What this means for gardeners: This isn’t a plant you should be casually adding to your garden wish list. Its extreme rarity means that any cultivation should only happen through official conservation programs with properly sourced, legally obtained plant material.

Should You Grow It?

The short answer is: probably not, and here’s why:

  • Extremely limited availability through legitimate sources
  • Likely requires very specific growing conditions that are difficult to replicate
  • Conservation efforts should take priority over private cultivation
  • May require special permits or authorization to grow legally

Better Alternatives for Your Hawaiian Garden

If you’re passionate about growing Hawaiian natives (and you should be!), consider these more readily available options that won’t strain wild populations:

  • Other Hedyotis species that are less rare
  • Native Hawaiian shrubs with similar growth habits
  • Locally recommended native plants from your nearest botanical garden or native plant society

How You Can Help

Instead of trying to grow this rare beauty, consider supporting conservation efforts:

  • Donate to Hawaiian plant conservation organizations
  • Volunteer with local botanical gardens or conservation groups
  • Choose abundant native alternatives for your landscaping
  • Spread awareness about Hawaii’s endangered plant species

The Bottom Line

The Waianae Range starviolet represents the incredible diversity of Hawaii’s native flora, but it’s also a sobering reminder of what we stand to lose. Rather than adding pressure to wild populations, let’s celebrate this plant by supporting the scientists and conservationists working to ensure its survival for future generations.

Sometimes the best way to love a plant is to admire it from afar and let the experts handle its care. The Waianae Range starviolet definitely falls into this category – a living treasure that’s better left to conservation professionals than backyard gardeners.
