Where other sunchokes produce clusters of small, knobby tubers that test your patience in the kitchen, White Mammoth throws large, chunky, smooth-skinned tubers that are as easy to harvest as potatoes and nearly as versatile to cook. The plants themselves are vigorous and towering, topped in late summer with a flush of golden sunflower blooms that light up the back of a border or garden edge and draw every native bee in the neighborhood. Plant it once in a sunny spot with decent drainage, and you will be harvesting for years.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLatin Name\u003c\/strong\u003e: Helianthus tuberosus 'White Mammoth'\u003cbr\u003e\u003cstrong\u003eSite and Soil\u003c\/strong\u003e: Full sun preferred, tolerates part shade; thrives in most kinds of soils\u003cbr\u003e\u003cstrong\u003ePollination Requirements\u003c\/strong\u003e: Self-fertile; an excellent late-season pollinator magnet when most other blooms have faded\u003cbr\u003e\u003cstrong\u003eSize at Maturity\u003c\/strong\u003e: 7–12' h x 2–3' w (best sited at the back of beds, along fencelines, or as a productive windbreak or privacy screen)\u003cbr\u003e\u003cstrong\u003eHarvest Time\u003c\/strong\u003e: Fall through winter; flavor and sweetness improve markedly after first frost — tubers can be left in the ground and dug as needed through the cool season\u003cbr\u003e\u003cstrong\u003ePests \u0026amp; Diseases\u003c\/strong\u003e: no meaningful pest or disease pressure\u003cbr\u003e\u003cstrong\u003eUSDA Zone\u003c\/strong\u003e: 3–9 (reliably perennial throughout Georgia; tops die back hard after frost and return with vigor each spring)\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eA Note on Spread: White Mammoth is a vigorous spreader — each year the planting will expand as unharvested tubers send up new shoots. This is a feature if you want a productive, self-sustaining patch, but if you're working with a defined bed or smaller garden space, plan to harvest thoroughly each fall or install a simple rhizome barrier at planting to keep it where you want it.\u003c\/p\u003e","brand":"New Earth Nursery","offers":[{"title":"Default Title","offer_id":42746109952071,"sku":null,"price":15.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0577\/5058\/5415\/files\/White_Mammoth_sunchoke_etsy_listing.png?v=1777729040","url":"https:\/\/newearthnursery.com\/products\/jerusalem-artichoke-sunchoke-white-mammoth-variety-helianthus-tuberosus-copy-copy","provider":"New Earth Nursery","version":"1.0","type":"link"}
