Wasabi (Wasabia japonica) is a prized Japanese root vegetable known for its sharp, clean spiciness and unique flavor used in sushi and Asian cuisine. This rare plant thrives in cool, shaded, and moist environments, producing heart-shaped leaves and thick rhizomes that can be grated into fresh wasabi paste. It’s a slow-growing perennial, ideal for containers, shaded gardens, or near water features where humidity is high.
