Green Ohba Ao Shiso

Shiso is an aromatic herb in the mint family that is used in Japanese cooking. This variety has broad flat green leaves on the upper and undersides and grows about 3' tall and bushy.  Also known as perilla, beefsteak leaf, and sesame leaf. Perilla readily reseeds itself, and can overtake disturbed areas. It is listed as a noxious weed in several US states, and is toxic to ruminant animals. Please take care when planting, and check your state's regulations before ordering these seeds! Days to maturity: 60-70 Seeds per pack: 195 Germination rate: 88% on 02/17/2026 Planting / harvesting notes Perilla seeds require sunlight to germinate well - do not cover them with soil! Direct sow after last frost, or sow indoors 4-6 weeks before last frost on the surface of moist potting soil. Pat down the seeds firmly, but do not cover. Keep lightly moist until germination. Transplant 12-24" apart. Harvest leaves early in the morning for best quality, flavor, and ability to keep in storage. Seed keeping notes Allow seedheads to dry on the plant. Cut the stalks below the lowest seed clusters. If necessary, dry the seedheads further in the sun on a sheet or table away from moisture and precipitation. When fully dry, whack the seedheads in a bucket, allowing the ripest seed to fall. Sift through strainers to remove the largest chaff, and then winnow off the lighter chaff with your breath, a fan, or the wind.
