{"product_id":"porcupine-grass-untrimmed-hesperostipa-spartea","title":"Porcupine Grass-Untrimmed (Hesperostipa spartea)","description":"\u003cp\u003ePorcupine Grass is a fascinating and structurally unique cool-season bunchgrass that adds dynamic movement to the prairie. Growing 2 to 4 feet tall, it is most famous for its extraordinary seeds, which feature long, twisted awns reaching up to 7 inches. These awns respond to humidity, literally drilling the seed into the soil—a remarkable natural engineering feat. Native to the central North American prairies, this grass thrives in full sun and well-drained, medium to dry soils. It provides essential cover for ground-nesting birds, while its early-season growth offers a lush green presence in spring. Because the sharp seeds can be hazardous to pets or livestock, it is best planted in managed natural areas. To grow from seed, a 60-day cold-moist stratification (C60) is recommended to ensure even germination in the spring.\u003c\/p\u003e\u003ch3\u003eQuick facts\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 2–4 ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSun:\u003c\/strong\u003e Full to Partial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil moisture:\u003c\/strong\u003e Medium to Dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBloom time:\u003c\/strong\u003e May–Jun (Green)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLife cycle:\u003c\/strong\u003e Perennial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNotes:\u003c\/strong\u003e Cool-season, Sharp seed- Caution!\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNative range:\u003c\/strong\u003e Native to 18 states, including Iowa, Minnesota, Wisconsin, Illinois, Missouri, Nebraska\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003ca href=\"https:\/\/database.hokseynativeseeds.com\/species\/hesperostipa-spartea\" target=\"_blank\"\u003eSee the full growing guide and county range map for Porcupine Grass-Untrimmed\u003c\/a\u003e\u003c\/p\u003e","brand":"Hoksey Native Seeds","offers":[{"title":"1 oz","offer_id":50926625751237,"sku":null,"price":12.0,"currency_code":"USD","in_stock":true},{"title":"1\/4 lb","offer_id":50926625784005,"sku":null,"price":47.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0752\/6567\/1365\/files\/hesperostipa-spartea-8309-3.jpg?v=1793734717","url":"https:\/\/hokseynativeseeds.com\/products\/porcupine-grass-untrimmed-hesperostipa-spartea","provider":"Hoksey Native Seeds","version":"1.0","type":"link"}
