Hardy to Zones 7 to 12

Herbaceous perennial native to mountain streams of Japan.  Our variety is MAZUMA, which is one of the main types–beautiful, vigorous and HOT.  This is the true wasabi. These cold-stored seeds must be planted in potting soil, about 1/2 inch deep, and mulched with coir or peat, and placed in COOL MOIST SHADE (not soaked in water or in running water or hydroponic setup, etc.) Germination of this summer or fall planted seed is in the very early spring. By March, the seedlings will have formed 2 sets of true leaves and its time to pot them up.  For example, I planted wasabi seeds 6/24/19 and they emerged on 2/16/20–nearly an 8 month induction period.   In colder climates, where the propagation beds may be frozen hard, germination will occur later, usually in April or perhaps as late as May. Please note that hard freezing of the germination beds or flats may prove to be harmful for the seed, so if winter temperatures go below 20 degrees F (Zone 7), greenhouse culture is advised. Plant prefers aquaculture or shaded beds of compost, misted daily. Space plants 1 foot apart.
