Hibiscadelphus: A Rare Hawaiian Native Tree Worth Knowing
If you’re passionate about native Hawaiian plants, you may have stumbled across the intriguingly named Hibiscadelphus ×puakuahiwi. This perennial tree represents one of Hawaii’s unique botanical treasures, though it remains shrouded in mystery for most gardeners.
What is Hibiscadelphus?
Hibiscadelphus ×puakuahiwi is a native Hawaiian tree that belongs to the hibiscus family. As a perennial woody plant, it typically grows with a single trunk and can reach impressive heights of over 13-16 feet under the right conditions. The × in its botanical name suggests this may be a natural hybrid, making it even more special in the world of Hawaiian botany.
Where Does It Come From?
This remarkable tree is endemic to Hawaii, meaning you won’t find it growing naturally anywhere else in the world. It’s part of Hawaii’s incredible native plant heritage that evolved in isolation over millions of years.
Should You Plant Hibiscadelphus in Your Garden?
Here’s where things get a bit complicated. While this native Hawaiian tree would theoretically make a wonderful addition to appropriate landscapes, there are some important considerations:
- Extremely limited availability – this species is not commonly found in nurseries
- Specialized growing requirements typical of Hawaiian endemics
- Best suited for Hawaiian or similar tropical climates
- May require specific soil conditions and care
Growing Conditions and Care
Like many Hawaiian native trees, Hibiscadelphus ×puakuahiwi likely thrives in:
- Warm, tropical climates (probably USDA zones 10-12)
- Well-draining soil
- Protection from strong winds
- Consistent moisture without waterlogging
Unfortunately, specific cultivation information for this particular species is quite limited, which brings us to an important point about rare native plants.
The Rarity Factor
Many plants in the Hibiscadelphus genus are critically endangered, and while we don’t have specific rarity information for H. ×puakuahiwi, it’s likely quite uncommon. If you’re fortunate enough to encounter this plant, it’s crucial to ensure any specimens are ethically and legally sourced.

The Bottom Line
