Menzies’ Ballart: A Rare Hawaiian Treasure Worth Protecting

Meet Menzies’ ballart (Exocarpos menziesii), a little-known Hawaiian native that’s as rare as it is special. Also called heau in Hawaiian, this unassuming shrub holds a precious place in Hawaii’s natural heritage—and unfortunately, it’s fighting for survival.

A Plant on the Edge

Before we dive into the gardening details, there’s something important you need to know: Menzies’ ballart is endangered. With a Global Conservation Status of S2 (Imperiled) and listed as Endangered in the United States, this perennial shrub has only 6 to 20 known occurrences remaining in the wild. If you’re considering adding this plant to your garden, please only source it through reputable native plant nurseries that use responsibly collected seeds or ethically propagated material.

Where You’ll Find This Hawaiian Endemic

Menzies’ ballart is found exclusively in Hawaii, making it a true island endemic. This special shrub grows naturally across several Hawaiian islands, including Hawaii (Big Island), Maui, Molokai, and Oahu, though its populations are severely limited.

What Does Menzies’ Ballart Look Like?

Don’t expect flashy flowers or bold foliage—this multi-stemmed woody shrub is all about subtle beauty. Typically reaching 13 to 16 feet in height (though it can grow taller in ideal conditions), Menzies’ ballart produces small, inconspicuous flowers followed by small red to orange berries. Its fine-textured foliage gives it a delicate, almost ethereal appearance that adds texture rather than bold color to the landscape.

Growing Menzies’ Ballart: For the Dedicated Gardener

Let’s be honest—this isn’t a plant for beginners. Menzies’ ballart has specialized growing requirements that can challenge even experienced gardeners:

  • Climate needs: USDA hardiness zones 10-11 (tropical conditions only)
  • Soil preferences: Well-drained volcanic soils
  • Light requirements: Partial shade to full sun
  • Growth rate: Slow-growing, requiring patience

Is This Plant Right for Your Garden?

Menzies’ ballart works best in specialized settings rather than typical home landscapes:

  • Native Hawaiian restoration projects
  • Cultural gardens celebrating Hawaiian heritage
  • Educational landscapes focusing on endangered species
  • Erosion control in appropriate native settings

Given its endangered status and challenging growing requirements, most home gardeners should consider supporting this species through conservation donations rather than attempting to grow it personally.

A Living Piece of Hawaiian Culture

Beyond its botanical significance, Menzies’ ballart represents an important connection to Hawaiian cultural heritage. The Hawaiian name heau reflects the deep relationship between native plants and traditional Hawaiian culture—a relationship that’s increasingly precious as these species become rarer.

Supporting Conservation Instead

If you’re passionate about Hawaiian native plants but want something more garden-friendly, consider these alternatives while supporting Menzies’ ballart conservation efforts:

  • Donate to Hawaiian native plant conservation organizations
  • Visit botanical gardens that maintain conservation collections
  • Choose other native Hawaiian plants that are more stable for home cultivation

Sometimes the best way to love a plant is to help protect it in its natural habitat rather than bringing it into our gardens. Menzies’ ballart reminds us that not every beautiful plant belongs in our backyard—some are meant to be wild treasures that we protect and admire from a respectful distance.
