Press shallow-sown seed into good soil contact and keep the seed zone from drying during establishment. Thin or transplant only when the growth habit and spacing call for it. Leave enough room for mature width and air movement. Bloom timing and final height can shift with sowing date, climate, soil, moisture, and competition, so use listed figures as planning ranges.\u003c\/p\u003e\n\u003cp\u003eThe Russian Mammoth Sunflower is the result of Russian breeding efforts and returned to the US in 1880 then as now under the name 'Russian Mammoth'.\u003c\/p\u003e\n\u003cp\u003eThis giant sunflower can grow easily to 10 inches in diameter.\u003c\/p\u003e\n\u003cp\u003ePlace Russian Mammoth Sunflower where its recorded height and growth habit fit the surrounding planting. Shorter companions can be positioned toward bed edges, while taller stems need room where they will not shade small seedlings too early. If cutting flowers, harvest with clean tools at the stage appropriate to the bloom form. If leaving flowers in place, observe how bloom sequence changes through the season and record which sowing date performed best at the site.\u003c\/p\u003e\n\u003cp\u003eExplore related options in our \u003ca href=\"\/collections\/flower-seeds\"\u003eFlower Seeds\u003c\/a\u003e.\u003c\/p\u003e","brand":"Grow Organic","offers":[{"title":"Pack","offer_id":53541791170849,"sku":"SWF8006","price":3.49,"currency_code":"USD","in_stock":true},{"title":"1\/4 lb","offer_id":53541791203617,"sku":"SWF8006B","price":20.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/8391\/9393\/files\/organic-sunflower-russian-mammoth-pack.jpg?v=1790015835","url":"https:\/\/inkivy.store\/products\/russian-mammoth-sunflower-seeds-organic","provider":"Ink \u0026 Ivy","version":"1.0","type":"link"}
