Growing Hinahina: Hawaii’s Native Geranium Worth Protecting

Meet hinahina (Geranium cuneatum var. hypoleucum), a charming native Hawaiian geranium that’s as unique as it is elusive. This perennial shrub represents one of nature’s special island adaptations, making it a fascinating addition for gardeners interested in authentic Hawaiian flora.

What Makes Hinahina Special

Hinahina belongs to the geranium family but has evolved specifically for Hawaii’s unique island conditions. As a multi-stemmed woody perennial, this shrub typically grows less than 13-16 feet tall with several stems emerging from near the ground. It’s exclusively native to Hawaii, making it a true island endemic that you won’t find growing naturally anywhere else in the world.

A Word of Caution: Rarity Matters

Before we dive into growing tips, there’s something important to know about hinahina. This plant has a Global Conservation Status of S3T3, indicating it’s considered rare or uncommon. If you’re interested in growing hinahina, it’s crucial to source plants only from reputable nurseries that propagate from legally and ethically obtained stock. Never collect from wild populations.

Is Hinahina Right for Your Garden?

Hinahina could be perfect for gardeners who:

  • Want to support native Hawaiian plant conservation
  • Are interested in rare and unique species
  • Live in Hawaii or similar tropical/subtropical climates
  • Appreciate the story and cultural significance of endemic plants

However, this plant might not be the best choice if you’re looking for something readily available at your local nursery or if you’re new to gardening with native species.

Growing Challenges and Considerations

Unfortunately, specific growing information for this variety of hinahina is quite limited, which reflects its rarity. As with many Hawaiian endemics, it likely prefers:

  • Well-draining soil
  • Protection from harsh winds
  • Appropriate moisture levels (not too wet, not too dry)
  • Climate conditions similar to its native Hawaiian habitat

Supporting Conservation Through Gardening

If you’re fortunate enough to find responsibly sourced hinahina, you’ll be participating in an important conservation effort. Growing rare native plants in cultivation helps preserve genetic diversity and can support future restoration projects. Just remember that with rarity comes responsibility – proper care and even propagation (when possible) can help ensure this special plant continues to thrive.

Alternative Native Options

If hinahina proves difficult to source, consider other native Hawaiian geraniums or consult with local native plant societies about similar endemic species that might be more readily available through conservation nurseries.

Growing hinahina is ultimately about more than just adding another plant to your garden – it’s about connecting with Hawaii’s unique natural heritage and supporting the preservation of irreplaceable island biodiversity.
