New! 120 days Uniform, smooth, snow-white roots reach to a foot long. Flavor is mild and sweet, particularly when harvested after fall frosts have transformed the starches they contain to sugars. Parsnips are another old-time staple crop that has largely fallen out of favor, but their sweet nutty flavor and excellent storage life (they can keep up to 5 months) recommend them for today’s gardens! 5,776 seeds/oz Pkt (~250 seeds) plants 10′.
