Mutant Tanoak: A Unique California Native Shrub for Your Garden
Meet the mutant tanoak (Notholithocarpus densiflorus attenuatodentatus) – and before you start picturing something from a science fiction movie, let me assure you this native California shrub is perfectly normal! The mutant in its common name simply refers to its distinctive leaf characteristics that set it apart from other tanoak varieties.
What Makes Mutant Tanoak Special?
This perennial shrub is a true California native, belonging to the oak family and representing a unique form of the well-known tanoak species. What distinguishes mutant tanoak is right there in its scientific name – attenuatodentatus refers to its leaves having gradually tapering, pointed teeth along their edges, giving it a distinctive appearance among native oaks.
As a multi-stemmed woody shrub, mutant tanoak typically grows to heights of 13-16 feet, though it can occasionally grow taller or develop a single trunk under the right environmental conditions. This growth habit makes it an excellent choice for gardeners looking for a substantial native shrub that can serve as a focal point or natural screen.
Where Does Mutant Tanoak Grow?
You’ll find this native beauty exclusively in California, where it has adapted to the state’s unique Mediterranean climate and diverse ecosystems. This limited distribution makes it a true California treasure and a perfect choice for gardeners wanting to showcase authentic regional flora.

There are several compelling reasons to consider adding mutant tanoak to your landscape:
- Native heritage: As a California native, it’s perfectly adapted to local conditions and supports regional ecosystems
- Unique character: Its distinctive leaf shape adds visual interest and conversation value to your garden
- Substantial presence: With its shrubby growth habit, it provides good structure and can serve multiple landscape functions

Growing Mutant Tanoak Successfully
While specific growing information for this particular form is limited, as a California native oak relative, mutant tanoak likely prefers conditions similar to other members of the oak family. Here are some general guidelines for success:
- Choose the right location: Plant in an area that receives adequate sunlight and has good drainage

Because mutant tanoak is a specific form of tanoak with limited distribution, finding this exact variety may require some detective work. Check with native plant societies, specialized nurseries, or botanical gardens in California for potential sources. If you can’t locate this specific form, consider the more widely available standard tanoak (Notholithocarpus densiflorus) as an alternative that offers similar benefits.
