Gray’s Cyrtandra: A Charming Native Hawaiian Shrub for Shade Gardens
If you’re looking to add a touch of authentic Hawaiian beauty to your shade garden, Gray’s cyrtandra (Cyrtandra grayi) might just be the perfect native shrub you’ve been searching for. This delightful endemic plant brings both ecological value and understated elegance to Hawaiian landscapes, making it a fantastic choice for gardeners who want to celebrate the islands’ natural heritage.
What is Gray’s Cyrtandra?
Gray’s cyrtandra is a perennial shrub that’s as Hawaiian as it gets – this beauty is found nowhere else in the world except across several Hawaiian islands including Kauai, Oahu, Molokai, and Maui. As a multi-stemmed woody plant, it typically stays manageable at under 13-16 feet tall, though most specimens remain much smaller in garden settings.
This native gem goes by the botanical name Cyrtandra grayi and has collected a few scientific synonyms over the years, including Cyrtandra lysiosepala varieties and Cyrtandra rotata. But don’t let the scientific names intimidate you – this is simply a lovely native shrub that deserves more attention in Hawaiian gardens.
Why Choose Gray’s Cyrtandra for Your Garden?
There are plenty of compelling reasons to consider this native Hawaiian shrub:
- Authentic native beauty: You’re supporting Hawaii’s unique ecosystem while creating an authentic island landscape
- Shade tolerance: Perfect for those tricky spots where other plants struggle in low light

Garden Design and Landscape Role
Gray’s cyrtandra shines as an understory shrub in shade gardens and native Hawaiian landscapes. Its glossy green foliage and compact growth habit make it an excellent choice for creating layers in tropical garden designs.

This shrub is particularly well-suited for native Hawaiian gardens, tropical landscapes, and any shade garden where you want to incorporate authentic island plants. It pairs beautifully with other native Hawaiian species and helps create habitat corridors for local wildlife.
Growing Conditions and Care
Gray’s cyrtandra is surprisingly accommodating once you understand its preferences. Here’s what this native beauty needs to thrive:

Interestingly, Gray’s cyrtandra has a facultative wetland status in Hawaii, meaning it can handle both wetland and non-wetland conditions. This flexibility makes it adaptable to various garden situations, as long as basic moisture needs are met.
