What is the Chameleon Plant?

Known by many names, including fish mint, fish wort, and heartleaf, the chameleon plant (Houttuynia cordata) is a herbaceous perennial recognized for its heart-shaped leaves and distinct, pungent aroma. A native of Southeast Asia, it is also notable for its ornamental value, with variegated leaves that display a mix of green, cream, red, and pink, especially in a sunny location. However, this ornamental quality comes with a major caveat for gardeners: it is an aggressive and invasive spreader through its vigorous underground rhizomes.

Origins and Traditional Use

For centuries, Houttuynia cordata has been a staple in traditional Chinese and Vietnamese medicine, valued for its antibacterial, anti-inflammatory, and detoxifying properties. Its use as a food source, eaten both raw and cooked, is deeply rooted in these cultures, particularly in southwestern China, Vietnam, Thailand, and parts of India.

The Flavor Profile and Culinary Applications

Those new to the chameleon plant are often surprised by its strong flavor, which can be divisive. The leaves and stems are described as having a unique citrus-pepper taste, with a prominent 'fishy' or 'coriander-like' aroma that is cherished in many Asian cuisines. The rhizomes also carry an edible, spicy flavor, often compared to ginger or galangal.

How to Eat the Chameleon Plant

Preparing chameleon plant for consumption involves a few simple steps. The tender young shoots, leaves, and rhizomes are the edible parts.

1. Harvesting: For the best flavor, harvest young leaves and shoots during the spring and summer. Rhizomes can be harvested year-round.
2. Cleaning: Rinse all parts thoroughly under cool, running water to remove dirt and any insects.
3. Preparation: Depending on the recipe, leaves can be used fresh, chopped, or blanched. Rhizomes should be scrubbed clean before cooking.

Popular culinary uses for the leaves include:

• Salads: Used sparingly as a garnish in fresh salads for a flavor punch.
• Garnishes: Chopped leaves are used to add zest to soups and noodle dishes.
• Spring Rolls and Wraps: Added to fresh spring rolls to balance other ingredients.
• Teas: Dried leaves, stems, and flowers can be brewed into an herbal tea, known as dokudami-cha in Japan.

Popular culinary uses for the roots (rhizomes) include:

• Stir-fries: In Chinese cuisine, especially in Guizhou, the rhizome (zhé'ěrgēn) is stir-fried with cured pork belly.
• Condiments: The raw or cooked roots can be used to make condiments or dipping sauces.
• Curries: Ground root is sometimes added to fish curries in Northeast India.

Potential Risks and Precautions

While the chameleon plant is generally considered safe to eat, certain precautions are necessary. The most significant issue for home gardeners is its invasive nature. If not contained, it can quickly take over a garden or other landscape, making it a persistent nuisance. Additionally, while most studies have found it non-toxic when consumed orally, some reports indicate that injectable extracts have caused severe allergic reactions. As with any strong-flavored food, the taste can be off-putting for some, so it's best to start with small amounts.

Comparison of Chameleon Plant Varieties

Flavor variations exist within the species Houttuynia cordata. The two main types are often distinguished by their origin and flavor profile, which can impact their culinary use.

| Feature | Chinese/Vietnamese Variety | Japanese Variety | Native Range | Southwest China, Vietnam | Nepal, Korea, Japan | Flavor Profile | Pungent, distinctly fishy or coriander-like aroma | Lemony, ginger-like aroma, less pungent | Common Use | Fresh leaves in salads, stir-fries with roots | Fresh leaves for garnishing sushi, salads, and soups |

Conclusion

Both the young leaves and roots can be incorporated into dishes like salads, stir-fries, and teas. While its distinctive 'fishy' or 'coriander' flavor might be an acquired taste for some, its nutritional and medicinal properties have been recognized for centuries. For home cultivators, it is critical to manage its aggressive, invasive growth to prevent it from overwhelming other garden plants. To get a better understanding of its growth habits and invasive tendencies, gardeners can consult resources from university extension programs or other horticultural institutions. Overall, the chameleon plant presents a fascinating culinary adventure for those willing to explore its bold and polarizing taste.
