The leaf coloring is distinct and beautiful: deep purplish-red on top with green undersides and red veins threading through. The flavor is a happy medium between mild mustard green, tender spinach, and Chinese cabbage — satisfying at any stage from tiny microgreen to full leafy head. Unlike many purple greens, this hybrid retains its deep purple color even in warm weather. Suitable for year-round growing where temperatures allow. 20–38 days.\u003c\/p\u003e\u003ch3\u003eWhy Grow Red Komatsuna Hybrid?\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat-tolerant hybrid\u003c\/strong\u003e — retains deep purple color even in warm conditions; grows well in all seasons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlazing fast\u003c\/strong\u003e — baby leaf in 20–38 days; microgreens even sooner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnique two-tone leaf color\u003c\/strong\u003e — deep purplish-red on top, green with red veins underneath; stunning in salads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSweet spinach flavor\u003c\/strong\u003e — a happy medium between mustard green, spinach, and Chinese cabbage; less bitter than most mustards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtraordinarily versatile\u003c\/strong\u003e — harvest at any stage from microgreens to full cabbage-like heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-season capable\u003c\/strong\u003e — sow any time the ground is workable; avoid peak summer heat for best results\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcellent for containers\u003c\/strong\u003e — compact rosette habit, ideal for pots and small-space gardens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerfect microgreens crop\u003c\/strong\u003e — vivid color and sweet flavor make it a standout in microgreen mixes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIn the Kitchen\u003c\/h3\u003e\u003cp\u003eConsume komatsuna at any stage — from delicate microgreens to tender baby leaves to full leafy heads.

Succession sow every 2–4 weeks for continuous harvest. For maximum yields of baby leaf, sow in 4-inch-wide shallow drills and harvest cut-and-come-again style. Thin seedlings once true leaves establish to desired spacing — 2–4 inches for baby leaf, up to 18 inches for full heads. Keep soil consistently moist; incorporate compost to improve fertility and moisture retention. Fertilize if leaves show pale color or poor venation. Tolerates full sun to full shade. Avoid peak summer heat for best color and flavor — part shade extends the season in warm weather. Outstanding for container growing. Harvest outer leaves when 8 inches tall for continuous production, or allow full head development and harvest like cabbage.\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDays to Maturity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20–38 days\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDays to Germination\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4–10 days\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePlant Height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12–18 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePlant Width\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5–20 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLeaf Color\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDeep purplish-red (top); green with red veins (underside)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFlavor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSweet spinach × mild mustard × Chinese cabbage; less bitter than most mustards\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHarvest Style\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMicrogreens, baby leaf, cut-and-come-again, or full head\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePlant Spacing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2–4 inches (baby leaf\/microgreens); up to 18 inches (full head)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRow Spacing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2–18 inches (depends on desired plant size)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePlanting Depth\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e¼–½ inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSoil\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAdaptable; fertile, moisture-retentive; amend with compost\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTemp Tolerance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20–85°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFull sun to full shade\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eColor Retention\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRetains deep purple in heat; loses color if overcooked — use quick cooking\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCommon Names\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eKomatsuna, Omatsuna, Mustard Spinach, Komatsu-na, Tender Green Mustard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUSDA Zones\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAll U.S. zones (annual)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLatin Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cem\u003eBrassica rapa\u003c\/em\u003e var. \u003cem\u003eperviridis\u003c\/em\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHybrid, Non-GMO, Annual\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003cem\u003ePacked and shipped by Box Garden Seeds LLC — heirloom seeds grown without GMOs, selected for flavor, resilience, and your garden’s success.\u003c\/em\u003e\u003c\/p\u003e","brand":"Box Garden Seeds LLC","offers":[{"title":"0.1 mg \/ 200+ Seeds","offer_id":50520103059590,"sku":"KSC\/F1-200-90-626-28-OT","price":3.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2669\/3330\/files\/red-komatsuna-plant-close-up.png?v=1775535109","url":"https:\/\/bgseedsllc.com\/products\/red-komatsuna-hybrid-seeds","provider":"Box Garden Seeds LLC","version":"1.0","type":"link"}
