Wasabi
Wasabi (Wasabia japonica / Eutrema japonicum)
A rare, shade‑loving perennial herb prized for its fiery flavour, culinary prestige, and lush, ornamental foliage
🌿 Wasabi is a unique perennial herb native to the cool, shaded mountain streams of Japan. Famous for its intense, aromatic heat, true wasabi is one of the most sought‑after culinary plants in the world — and surprisingly, it can be grown successfully in the UK with the right conditions. Its large, Round/heart shaped leaves and elegant, clumping habit make it as attractive as it is useful. Slow‑growing but rewarding, wasabi is a standout addition to shady gardens, damp borders, and woodland‑style plantings.
True wasabi offers a clean, sharp heat very different from the dyed horseradish pastes commonly sold as “wasabi”.
Rhizome (the prized part)
• Grated fresh to produce authentic wasabi paste
• Best used immediately, as flavour fades within minutes
• Ideal with sushi, sashimi, noodles, grilled fish, and tempura
Leaves & Stems
• Edible with a mild wasabi kick
• Used in salads, stir‑fries, pickles, and tempura
• Young leaves can be eaten raw; older leaves are best cooked
Flowers
• Small white flowers with a delicate peppery flavour
• Used as a garnish or added to salads
🔥 Flavour profile: clean, aromatic heat with a sweet, green freshness — not the harsh burn of imitation wasabi.
