Item Details

This beautiful, purple-green leaf mustard is ideal for salads. Its highly blistered, downward-curling leaves are pungent like wasabi, yet sweet, juicy, and crisp. Donated to Seed Savers Exchange in 2002 by member Kazumitsu Tsutsui of Kagawa, Japan, this variety is quite popular on the Exchange, where it has been shared since 1997. Plants reach 16-19" tall and 19-28" wide at maturity and perform best when sown in summer for fall harvest. 80 days.

Learn to Grow Hyakka Mustard

Start Indoors: 6 weeks before last frost

Direct Seed: 1/2" Deep

Thin: 1-6" Apart

Plant Outdoors: 6-8” Apart

You can directly seed your mustards into the ground, placing 3 seeds every 8 inches. Plant them 3 months before your first frost in rows 18-30 inches apart. The seeds should be planted 1/4-1/2 inch deep. As they grow, thin them to 1 plant every 8-10 inches. Mustards may bolt early if planted in the spring.

Not my top choice, but . . .


Grew well enough for me in one of my raised beds in SE Iowa. I prefer another mustard I purchased from SSE because of its faster growth and better flavor. BUT this mustard is beautiful! This mustard does taste good and is worth a spot in your garden if you have room for more than one mustard.
