Edible Qualities

Wasabi is a perennial vegetable plant that is typically grown for its edible qualities. The entire above-ground parts of the plant are edible, and are usually harvested from mid to early winter. The edible parts have a hot taste and a spicy fragrance.

The plant is most often used in the following ways:

  • Fresh Eating
  • Eating When Cooked/Prepared
  • Cooking
  • Preserves

Planting & Growing

Wasabi will grow to be about 24 inches tall at maturity, with a spread of 24 inches. When planted in rows, individual plants should be spaced approximately 12 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years.

This plant is typically grown in a designated vegetable garden. It does best in partial shade to shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. This species is not originally from North America.

Wasabi is a good choice for the vegetable garden, but it is also well-suited for use in outdoor pots and containers. It can be used either as 'filler' or as a 'thriller' in the 'spiller-thriller-filler' container combination, depending on the height and form of the other plants used in the container planting. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
