Ipomoea batatas 'Beauregard'
vegetableBeauregard is the most popular home-garden sweet potato, a vigorous, dependable variety with rosy-copper skin and sweet, moist, deep-orange flesh that bakes and roasts beautifully. A heat-loving tropical vine grown for its swollen storage roots, it is among the earlier sweet potatoes, maturing in about 90 to 105 days, and the sprawling vines also yield edible leaves.

Sweet potatoes are grown from rooted sprouts called slips, set out a few weeks after the last frost once the soil is thoroughly warm, since the vines are killed by cold. Plant slips in loose, well-drained soil, ideally in mounded ridges, in full sun, spacing them about a foot apart, and give the rambling vines room to run. They thrive in summer heat and tolerate some drought, needing little fertilizer, since too much nitrogen grows vines at the expense of roots.

Row cover young plants until the vines run
Dig the roots before the first frost, usually when the vines begin to yellow, loosening the soil carefully with a fork since the thin skins bruise easily. Cure the freshly dug roots for about a week to ten days in a warm, humid place around 80 to 85F, which heals nicks and converts starch to sugar, then store at about 55 to 60F, where they keep for months and grow sweeter.
Sweet potatoes are an exceptional source of vitamin A, with one root supplying several times the daily value from beta-carotene, plus vitamin C, potassium, fiber, and B6, all with a naturally sweet flavor and no fat.
