Alternatively, sow seeds in outdoor containers in the fall or winter, with germination occurring in the spring. If seed is untreated by February, we recommend artificially moist stratifying in a fridge.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eSeeds of this species appreciate being covered by a thin layer of soil or buried lightly when sown to aid in germination. A general rule of thumb is to cover them with a layer of soil no more than two to three times their width. However, it's better to plant seeds shallow, and most seeds will germinate even if surface sown. (Optional) Sprinkling a layer of sterile sand or vermiculite overtop the soil and sown seeds usually won't negatively impact germination, and may help to maintain soil moisture and deter mold.\u003c\/p\u003e","brand":"Woolly Bear Natives","offers":[{"title":"Default Title","offer_id":52945742004531,"sku":"SD-SILAST-PKT","price":5.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/4212\/0499\/files\/silphium-asteriscus.avif?v=1768237557","url":"https:\/\/woollybearnatives.com\/products\/silphium-asteriscus-whorled-rosinweed-seed-packet","provider":"Woolly Bear Natives","version":"1.0","type":"link"}
