Its loose growth makes it easy to gather young greens or cut a larger plant for soup, braising and stir-frying. Traditionally used in Japanese cooking, it is especially useful where a tender leafy cabbage is preferred. Small successive plantings supply fresh greens without requiring every plant to reach full size at once.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eA mild, leafy cabbage for soups, salads and quick cooking.\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eGrowing facts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBotanical name:\u003c\/strong\u003e Brassica rapa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaturity or display:\u003c\/strong\u003e 40-60 days\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature size:\u003c\/strong\u003e Loose leafy rosette; size varies with harvest stage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpacing:\u003c\/strong\u003e 12 in between plants; rows 18 in\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout the variety\u003c\/h2\u003e\n\u003cp\u003eOsaka Shirona belongs to the Japanese shirona group of leafy Brassica rapa vegetables. Supplier descriptions of a possible cabbage\/pak choi cross are tentative, not a verified breeding pedigree. The packet uses the supported species name and avoids equating it with every komatsuna strain.\u003c\/p\u003e\n\u003ch2\u003eStarting seed\u003c\/h2\u003e\n\u003cp\u003eSow 1\/4-1\/2 in. deep for mild spring weather or late-summer planting. Keep moist at 60-70 F; allow about 4-10 days to sprout. Thin to 12 in. apart, rows 18 in. apart. Use sun and fertile soil; prolonged cold or heat may trigger bolting.\u003c\/p\u003e\n\u003ch2\u003eCare through the season\u003c\/h2\u003e\n\u003cp\u003eMaintain even moisture and remove weeds while small. Rotate brassica beds and use insect netting before flea beetles or caterpillars arrive. Grow for a cool harvest; extended cold on young plants can induce flowering, and summer heat can reduce leaf quality. Fall sowings often avoid spring cold followed by heat.\u003c\/p\u003e\n\u003ch2\u003eHarvest and use\u003c\/h2\u003e\n\u003cp\u003ePick tender outer leaves or cut plants above the soil at a useful size, about 40-60 days from sowing. Refrigerate; loose leaves are best used soon. Save seed from several healthy plants isolated from other flowering Brassica rapa; dry mature pods before threshing.\u003c\/p\u003e\n\u003ch2\u003eSaving seed\u003c\/h2\u003e\n\u003cp\u003eThese open-pollinated brassicas are insect-pollinated. Keep several healthy, typical plants for seed and prevent crossing with other flowering varieties of the same species. Some plants need a cold period before flowering. Let pods mature, then cut and dry them under cover before they shatter; clean, label and store seed cool and dry.\u003c\/p\u003e\n\u003ch2\u003eCommon problems\u003c\/h2\u003e\n\u003cp\u003eCheck young leaves for flea beetle holes, aphids and caterpillars. Use row covers early, inspect regularly, and remove badly diseased plants. Crop rotation, drainage and steady watering help limit root disease and stress. A flowering stem means the leafy harvest is ending; use the leaves promptly.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eDoes it form a tight head?\u003c\/h3\u003e\n\u003cp\u003eOsaka Shirona pairs broad, bright green leaves with flat white stalks for a mild, crisp cabbage harvest.\u003c\/p\u003e\n\u003ch3\u003eWhen should I harvest?\u003c\/h3\u003e\n\u003cp\u003ePick tender outer leaves or cut plants above the soil at a useful size, about 40-60 days from sowing.
