Eggshape Melicope: A Rare Hawaiian Native Worth Protecting in Your Garden

Meet the eggshape melicope (Melicope ovata), a charming Hawaiian native shrub that’s as unique as its name suggests. This unassuming beauty might not be the showiest plant in the garden center, but it’s got something special going for it – it’s a true Hawaiian endemic that’s fighting for survival in the wild.

What Makes Eggshape Melicope Special?

This perennial shrub is one of Hawaii’s botanical treasures, found nowhere else on Earth. Also known by its scientific synonyms Pelea glabra and Pelea ovata, this multi-stemmed woody plant typically stays under 13-16 feet tall, making it perfect for smaller gardens and understory plantings.

The eggshape melicope produces small, delicate white to cream-colored flowers that may seem modest at first glance, but they’re incredibly important to Hawaii’s native ecosystem. Its glossy green leaves add year-round interest, and the compact growth habit makes it an excellent choice for adding structure to native plant gardens.

Where Does It Come From?

Melicope ovata is endemic to Hawaii, meaning it evolved here and calls these islands home exclusively. You’ll find it growing naturally in Hawaii’s native forests, where it plays an important role in the understory ecosystem.

A Word of Caution: This Plant Needs Our Help

Here’s something important every potential grower should know: eggshape melicope has a Global Conservation Status of S3, which means it’s considered vulnerable. With only an estimated 3,000 to 10,000 individuals remaining in the wild, this species is at risk of disappearing forever.

If you choose to grow this plant, please only purchase from reputable native plant nurseries that propagate from ethically sourced material. Never collect plants or seeds from wild populations – every plant in the wild is precious for the species’ survival.
