It grows 1 to 2 feet tall and forms dense clumps of slender, dark green stems from a dense, far-reaching matrix of black rhizomes. It thrives in saline or brackish soils and is highly tolerant of salt spray, typically establishing just above the high-tide line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCoastal salt marsh restoration - stabilizes soils in saline conditions\u003c\/li\u003e\n\u003cli\u003eUpper intertidal zone plantings, just above the high-tide line\u003c\/li\u003e\n\u003cli\u003eErosion control on saline, brackish shorelines\u003c\/li\u003e\n\u003cli\u003eWildlife habitat for shorebirds and other saltmarsh species\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eGrowing Conditions \/ Specification Data\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight:\u003c\/strong\u003e Full Sun\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil\/Moisture Tolerance:\u003c\/strong\u003e Saline, waterlogged soils; highly tolerant of salt spray but intolerant of prolonged flooding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant Type:\u003c\/strong\u003e Graminoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature Height:\u003c\/strong\u003e 1-2 ft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFall Color:\u003c\/strong\u003e Insignificant\/None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBloom Color \/ Period:\u003c\/strong\u003e Insignificant\/None; June-September\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetland Indicator Status:\u003c\/strong\u003e OBL (Obligate Wetland, regional source) - see flags\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNative Range:\u003c\/strong\u003e Coastal North America\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydrology:\u003c\/strong\u003e Moist-Wet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoot Depth:\u003c\/strong\u003e Shallow (Under 12 in.)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Rate:\u003c\/strong\u003e Moderate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrought Tolerance:\u003c\/strong\u003e Low\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeer Resistance:\u003c\/strong\u003e Yes (Rarely Damaged)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShade Tolerance:\u003c\/strong\u003e Intolerant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSalinity Tolerance:\u003c\/strong\u003e High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlood Tolerance:\u003c\/strong\u003e Low - IMPORTANT: despite being a salt marsh species, this rush establishes just above the high-tide line in the upper marsh zone and prefers saline, waterlogged soils - but is explicitly documented as intolerant of flooding itself, distinct from the regularly-inundated low marsh species it grows alongside.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Habit:\u003c\/strong\u003e Spreading - rhizomatous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSDA Hardiness Zones:\u003c\/strong\u003e 4-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePollinator Value:\u003c\/strong\u003e None significant - wind-pollinated\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pinelands Nursery","offers":[{"title":"50 Cell 2\" Plug","offer_id":48941164232775,"sku":"JUN-GER 50CELL","price":82.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/1649\/7991\/files\/JUNCUSGERARDII3.jpg?v=1792170843","url":"https:\/\/www.pinelandsnursery.com\/products\/juncus-gerardii-black-grass","provider":"Pinelands Nursery","version":"1.0","type":"link"}
