Molokai Mirrorplant: A Rare Hawaiian Native Worth Protecting

Meet the Molokai mirrorplant (Coprosma ternata), a charming Hawaiian native that’s as special as it is rare. This understated shrub might not win any flashy flower contests, but it’s got something far more valuable—it’s a genuine piece of Hawaii’s natural heritage that deserves a spot in every native garden.

What Makes Molokai Mirrorplant Special?

This perennial shrub is endemic to Hawaii, meaning you won’t find it growing wild anywhere else on Earth. The Molokai mirrorplant typically grows as a multi-stemmed woody plant, reaching heights of 4 to 5 meters (13 to 16 feet) under ideal conditions, though it often stays more compact in garden settings.

What sets this plant apart is its distinctive leaf arrangement—glossy green leaves arranged in groups of three around the stems, giving it a neat, organized appearance. The small white or greenish flowers may be modest, but they’re followed by colorful red to orange berries that add visual interest to the landscape.

Where Does It Grow?

As its name suggests, the Molokai mirrorplant is native to Hawaii, with its natural range primarily on the island of Molokai. This limited distribution makes it particularly precious in the world of native plants.

Important Conservation Note

Here’s something every gardener should know: Molokai mirrorplant has a Global Conservation Status of S2?, indicating it’s considered rare and potentially vulnerable. This means if you’re thinking about adding this beauty to your garden, you’ll want to source it responsibly. Always purchase from reputable native plant nurseries that propagate their own stock rather than collecting from wild populations.

Why Grow Molokai Mirrorplant?

There are several compelling reasons to consider this Hawaiian native:

  • Supports native Hawaiian ecosystems and wildlife
  • Excellent for understory plantings in shaded areas
  • Helps prevent soil erosion with its root system
  • Low-maintenance once established
  • Attracts native Hawaiian insects and pollinators
  • Perfect for authentic Hawaiian landscape designs

Growing Conditions and Care

The Molokai mirrorplant thrives in Hawaii’s tropical climate (USDA hardiness zones 10-12). Here’s how to keep it happy:

Light Requirements: This shrub prefers partial shade to full shade, making it perfect for those tricky spots under larger trees or on the north side of buildings.

Soil Needs: Well-draining soil is essential. Hawaiian volcanic soils work well, but any good garden soil with proper drainage will suffice.

Water Requirements: Consistent moderate moisture is key. Don’t let it dry out completely, but avoid waterlogged conditions.

Planting and Care Tips

Getting your Molokai mirrorplant established is straightforward:

  • Plant during Hawaii’s cooler months for best establishment
  • Apply a layer of organic mulch around the base to retain moisture
  • Water regularly during the first year while roots establish
  • Minimal pruning is needed—just remove dead or damaged branches
  • Feed with a balanced fertilizer occasionally, but don’t overdo it

Garden Design Ideas

The Molokai mirrorplant shines in native Hawaiian landscape designs. Use it as an understory shrub beneath taller native trees, or plant it in groups for a natural woodland feel. It’s also excellent for restoration projects and creating wildlife habitat in residential gardens.

Consider pairing it with other native Hawaiian plants like ʻōhiʻa lehua, koa, or native ferns for an authentic island garden that supports local ecosystems.

The Bottom Line

While the Molokai mirrorplant might not be the showiest plant in your garden, it offers something increasingly rare—authenticity and ecological value. By growing this native Hawaiian species, you’re not just adding another plant to your landscape; you’re participating in conservation efforts and supporting Hawaii’s unique natural heritage.

Just remember to source your plants responsibly from established nurseries, and you’ll be contributing to the preservation of this special species for future generations to enjoy.
