About Green
Green is an annual selection of shiso, with an upright/erect habit and an expected height or spread of 25–30 in. It is best suited to culinary leaves, flowers, or seed and succession planting. Notable traits include harvest leaves young or allow selected plants to mature seed according to use; aromatic flavor characteristic of the named herb.
Gardeners comparing named strains should evaluate Green for uniformity, flavor, timing, and plant form rather than assuming another shiso will perform identically.
History and provenance
This herb has been selected in regional foodways for aroma, acidity, sweetness, color, or leaf use. Cultural context is retained where it is well established, but a commercial name alone does not prove a breeder, community, or accession history for the packet now being sold. Green Shiso (Perilla frutescens var. crispum) Origins and Etymology Green Shiso, also known as Ao Shiso in Japan and Perilla frutescens var. crispum in botanical Latin, belongs to the mint family (Lamiaceae). Native to the mountainous regions of East Asia, particularly China, Korea, and Japan, Shiso has been cultivated for centuries as both a culinary and cultural treasure. Its close relatives include wild perilla species that grew along the Yangtze River Basin thousands of years ago, later spreading through trade and migration across the continent. The name Perilla is derived from the Latin perilla, a diminutive of pera, meaning “little bag,” likely referencing the plant’s seed pods. In Japanese, shiso (紫蘇) translates to “purple revival,” originally tied to the red-leaf form’s association with vitality and renewal in early herbal lore. Whether used fresh in salads, as a garnish, or in traditional Japanese dishes like sushi and tempura, Green Shiso adds a distinctive flavor profile that elevates any dish.

Starting Green from seed
Sow 1/4 in deep and keep the seed zone evenly moist. Expect emergence in 7-14 Days when the seed-zone temperature is near 55–70 °F. Germination preparation: Use a fine, evenly moist seed-starting mix or prepared seedbed. Light requirement: Cover evenly to 1/4 in. Soaking: None required. Stratification: None required. Scarification: None required.
Planting and care
Plant during spring and provide full sun. Space plants 8 in apart with 18 in between rows. Use loamy with a pH near 6.0–6.5, and follow a moderate watering plan. Support requirement: No-Support. Frost response: Semi-Hardy. Medium to large container or in-ground bed; avoid crowding
Harvest and use
Approximately 70-79 Days, from direct sowing to the primary leaf, flower, or seed harvest stage. Weather, soil temperature, and planting method can shift the actual harvest date. Harvest: Harvest leaves young or allow selected plants to mature seed according to use. Uses: Culinary leaves, flowers, or seed and succession planting. Flavor: aromatic flavor characteristic of the named herb. Seed saving: Open-pollinated herb or leafy crop. Best uses include culinary leaves, flowers, or seed and succession planting. Flavor and eating quality: aromatic flavor characteristic of the named herb.
Saving seed
Select several healthy, true-to-type Green plants that match the expected upright/erect habit and overall plant form. Avoid saving seed only from the earliest or largest individual unless that is your deliberate selection goal. Pollination system: Open-pollinated herb or leafy crop. Compatible plants of the same species may cross to varying degrees through insects or wind. Separate compatible varieties that may flower together, or use cages, barriers, hand pollination, or another documented control appropriate to the crop. Allow selected plants to pass the eating stage and reach full botanical seed maturity. Harvest only when seed heads, pods, or fruits have matured enough for sound seed development. Clean the seed carefully, dry it thoroughly away from direct heat, label the lot with variety and year, and store it cool, dark, and dry. Test germination before an important planting or distribution season.
Common problems
Common concerns: Aphids, whiteflies, spider mites, slugs, damping-off, root rot, and leaf diseases under humid crowded conditions. Management: Provide airflow, drainage, moderate fertility, careful watering, and clean harvest practices. Contain spreading mints where needed. Diagnosis note: Similar symptoms can have different causes. Compare plants of the same age, record weather and irrigation, and use local Extension or diagnostic support before applying a control.
