Cliff-Dwelling Starviolet: Hawaii’s Hidden Treasure in Need of Protection

Tucked away in Hawaii’s remote landscapes lives one of the island’s most elusive botanical treasures: the cliff-dwelling starviolet (Hedyotis flynnii). This isn’t your typical garden center find—in fact, you’d be incredibly fortunate to ever encounter this rare native Hawaiian shrub in the wild.

What Makes This Plant So Special?

The cliff-dwelling starviolet is a perennial shrub that’s endemic to Hawaii, meaning it exists nowhere else on Earth. As a member of the coffee family (Rubiaceae), this multi-stemmed woody plant typically stays under 13-16 feet tall, with several stems emerging from near the ground level.

But here’s what makes this plant truly remarkable: it’s critically imperiled. With a Global Conservation Status of S1, the cliff-dwelling starviolet is hanging on by a thread, with typically five or fewer known populations and fewer than 1,000 individuals remaining in the wild.

Where Does It Call Home?

This rare beauty is found exclusively in Hawaii, where it likely inhabits specialized cliff and rocky environments—hence its evocative common name. The plant has adapted to Hawaii’s unique island ecosystem over thousands of years.

Should You Plant Cliff-Dwelling Starviolet?

Here’s where we need to have a serious conversation about conservation. While the allure of growing such a rare native plant might be tempting, the cliff-dwelling starviolet’s critically imperiled status means it requires our protection, not our cultivation attempts.

The Reality of Rarity

With so few individuals left in the wild, every plant matters for the species’ survival. Unless you’re working with:

  • Authorized conservation organizations
  • Botanical gardens with conservation programs
  • Responsibly sourced material from legitimate propagation efforts
  • Proper permits and expertise

It’s best to admire this plant from afar and support conservation efforts instead.

What We Don’t Know (And Why That Matters)

The cliff-dwelling starviolet’s extreme rarity means we have limited information about many aspects of its biology, including:

  • Specific growing requirements
  • Pollinator relationships
  • Propagation methods
  • Wildlife benefits
  • Exact habitat preferences

This knowledge gap is precisely why professional conservation efforts are so crucial for this species’ survival.

How You Can Help

Instead of attempting to grow cliff-dwelling starviolet, consider these alternatives:

  • Support Hawaiian native plant conservation organizations
  • Choose other native Hawaiian plants for your garden that aren’t critically imperiled
  • Visit botanical gardens that participate in rare plant conservation
  • Spread awareness about Hawaii’s endangered flora

The Bigger Picture

The cliff-dwelling starviolet represents the fragile nature of island ecosystems and the importance of biodiversity conservation. While we can’t offer growing tips for this rare gem, we can appreciate its existence and work to ensure future generations might have the chance to encounter it in Hawaii’s wild places.

Sometimes the most responsible way to love a plant is to let it be—and to support the dedicated conservationists working to keep species like the cliff-dwelling starviolet from disappearing forever.
