Wasabi seeds grow into unique perennial plants known for their pungent rhizomes, widely used to make the famous green paste accompanying sushi. Wasabi belongs to the Brassicaceae family and features heart-shaped leaves with small white flowers. While traditionally cultivated in cool, shaded, and moist environments, wasabi can also be grown successfully in containers or shaded garden beds by committed gardeners.

Planting Tips for Wasabi
Sow seeds in a moist seed-starting mix and keep at a steady temperature around 55F (13C). Germination can take 38 weeks, so patience is key. Transplant young plants into deep containers or shady outdoor beds with constant access to moisture. Mulch heavily to help retain soil temperature and humidity.
