Wasabi – Wasabia japonica

Wasabi is a rare, cool-climate plant prized for its spicy rhizomes, used in traditional Japanese cuisine. Unlike store-bought wasabi substitutes, homegrown wasabi delivers a complex, fresh heat with a unique, aromatic flavor. This shade-loving perennial thrives in cool, humid environments, making it ideal for shaded gardens, greenhouses, and indoor hydroponic setups. Its lush, heart-shaped leaves are also edible and add a mild, wasabi-like zest to salads and dishes.
Care & Maintenance:

• Wasabi requires constant moisture but well-draining, organic-rich soil to prevent rot.
• It thrives in temperatures between 10-20°C, making it perfect for New Zealand’s cooler regions like the South Island, Wellington, and shaded areas of the North Island.
• Water consistently, provide good airflow, and fertilize regularly for strong growth.
• Expect harvestable rhizomes in 18-24 months.

Grow your own fresh, real wasabi at home and enjoy an authentic, gourmet culinary experience!
