Cheesewood: A Native Hawaiian Tree Worth Discovering

If you’re looking for a unique native Hawaiian tree to add to your landscape, you might want to get acquainted with cheesewood (Pittosporum ×monae). This perennial woody plant represents one of Hawaii’s lesser-known native treasures, and while it may not be as famous as some of its island neighbors, it has plenty to offer the right gardener.

What is Cheesewood?

Cheesewood is a native Hawaiian tree that typically grows as a single-trunked specimen, usually reaching heights greater than 13-16 feet under ideal conditions. Like many trees, it can sometimes develop a multi-stemmed or shorter growth form depending on environmental factors. As a hybrid species (indicated by the × in its botanical name), this plant represents a natural cross between two Pittosporum species.

Where Does Cheesewood Grow?

This tree is exclusively native to Hawaii, where it has adapted to the unique island ecosystem over time. Its natural range is limited to the Hawaiian Islands, making it a true endemic species.

Should You Plant Cheesewood?

As a native Hawaiian species, cheesewood offers several advantages for local gardeners:

  • It’s naturally adapted to Hawaiian growing conditions
  • Supporting native plants helps preserve local ecosystems
  • Native species often require less water and maintenance once established
  • You’ll be growing something truly unique to the islands

However, there are some considerations to keep in mind. Information about this particular hybrid is limited, which means you might be taking on a bit of a gardening adventure. If you prefer plants with well-documented growing requirements and predictable characteristics, you might want to start with better-known native Hawaiian species first.

Growing Cheesewood Successfully

Since detailed growing information for this specific hybrid is scarce, your best approach is to provide conditions similar to those preferred by other native Hawaiian Pittosporum species:

General Growing Tips

  • Plant in well-draining soil
  • Provide protection from strong winds when young
  • Water regularly during establishment, then reduce as the tree matures
  • Choose a location with adequate space for a tree that may reach 13+ feet

Landscape Role

As a native tree, cheesewood works well in:

  • Native plant gardens
  • Restoration projects
  • Mixed native landscapes
  • Areas where you want to support local wildlife

The Bottom Line

Cheesewood represents an opportunity to grow something truly special – a native Hawaiian hybrid that you won’t find anywhere else in the world. While detailed growing information is limited, this can be part of the appeal for adventurous gardeners who want to contribute to preserving Hawaii’s unique plant heritage.

If you’re interested in trying cheesewood, consider reaching out to local native plant societies or botanical gardens for advice and potentially sourcing material. They may have insights about growing this particular species that aren’t widely available in general gardening resources.

Remember, every native plant you grow is a small contribution to maintaining the incredible biodiversity that makes Hawaii’s landscapes so special.
