Island-Daisy: Hawaii’s Hidden Native Gem

If you’re passionate about native Hawaiian plants, you’ve probably heard of the more famous natives like ʻōhiʻa lehua or naupaka. But have you ever encountered the charming island-daisy? This lesser-known native, scientifically called Keysseria, represents one of Hawaii’s unique botanical treasures that deserves more recognition in native landscaping.

What Makes Island-Daisy Special?

Island-daisy is a perennial forb herb—essentially a soft-stemmed flowering plant that comes back year after year. Unlike woody shrubs or trees, this herbaceous beauty puts its energy into flowers and foliage rather than developing thick, woody stems. It’s what botanists call a forb, which is just a fancy way of saying it’s a broadleaf flowering plant that isn’t a grass.

Where You’ll Find Island-Daisy

This plant is exclusively native to Hawaii, making it a true endemic species. You won’t find Keysseria growing naturally anywhere else in the world—it’s as Hawaiian as it gets! Currently, island-daisy grows throughout the Hawaiian islands, representing an important part of the archipelago’s unique flora.

Why Consider Island-Daisy for Your Garden?

Here’s where things get a bit tricky—and honestly, quite intriguing. Island-daisy is somewhat of a mystery plant in the horticultural world.
