Bog Colicwood: A Rare Hawaiian Treasure for Specialized Gardens
Meet bog colicwood (Myrsine denticulata), one of Hawaii’s lesser-known native shrubs that’s as intriguing as it is elusive. This unassuming plant might not win any beauty contests, but it holds a special place in Hawaii’s unique ecosystem – and deserves our respect and protection.
What Makes Bog Colicwood Special?
Bog colicwood is a perennial shrub that’s exclusively native to the Hawaiian Islands. True to its name, this plant has carved out its niche in Hawaii’s boggy, wetland areas where few other plants dare to grow. It’s a multi-stemmed woody plant that typically stays under 13-16 feet tall, though it usually grows much smaller in its challenging bog habitat.
Where You’ll Find It (If You’re Lucky)
This Hawaiian endemic grows only in Hawaii, making it a true island treasure. You’ll find bog colicwood in wetland areas throughout the islands, where it’s adapted to the unique conditions of Hawaiian bogs.
A Word of Caution: Rarity Matters
Important: Bog colicwood has a Global Conservation Status of S1S2, meaning it’s critically imperiled to imperiled in its native range. This is a rare plant that faces conservation challenges, so if you’re considering adding it to your garden, please proceed thoughtfully.

Responsible Sourcing is Key
