Types
The fastest-growing sweet potato varieties have orange flesh, but you might also consider varieties with white, yellow, or even purple flesh. Note that orange-flesh varieties cook up moist; white and yellow sweet potatoes become creamy; purple sweets are dry and starchy.
- ‘Beauregard’ (90 days) originally comes from Louisiana, but grows well in the North, too. It has dark red roots, dark orange flesh, and stores well.
- ‘Bush Porto Rico’ (110 days) is good for small gardens and for baking.
- ’Centennial’ (100 days) is the leading variety in the U.S. It is carrot-colored and has a good storage life; good producer for northern growers.
- ‘Georgia Jet’ (90 days) has red skin that covers moist, deep orange flesh. It is an extremely fast-growing type; good for the North.
- ‘Jewel’ (120 days) has copper-colored skin and orange flesh; disease-resistant; stores well.
- ‘Stokes’ (120 days) offers a vibrant purple color and is full of extra health benefits; cooks well in savory dishes and mashes.
- ‘Vardaman’ (110 days) is a bush type and good for small gardens; it has unique blue/purple foliage, golden skin, and reddish-orange flesh; stores well.
- ‘White Yam’ (aka ‘White Triumph’)(100 days)has white skin covering dry white flesh; one of the oldest sweet potato varieties; has compact vines.

Cooking Notes
Relatively low in calories, sweet potatoes are very nutritious, a top source of beta-carotene, and contain some protein, calcium, iron, vitamins A and C, and other minerals. They can be stored longer than winter squash.
To cook, sweet potatoes are easier than pie (or sweet potato pie!).
- They can be scrubbed, poked with a fork in a few places, and baked at 400°F for 35 minutes to 1 hour, until they give a bit when you squeeze them in your pot-holder–protected hand.
- In the microwave, a whole sweet potato baked on high should be ready in 4 to 6 minutes. It may still feel firm when done; let it stand for about 5 minutes to soften.
- Sweet potatoes can also be steamed whole (cleaned and unpeeled) for about 40 minutes or until tender or cooked whole (cleaned and unpeeled) in boiling salted water for about 35 minutes. (Boiling reduces the flavor considerably.)
- Immerse cut raw sweet potatoes in water until you’re ready to cook them; they will darken otherwise.
As a general rule, don’t substitute sweet potatoes for regular potatoes in recipes; the two aren’t related. Sweet potatoes don’t hold together the way potatoes do, and their strong flavor can overwhelm a dish meant for a milder potato taste. Sweet potatoes are also not related to yams. But they make a fine substitute for pumpkin, especially in desserts.

Cut the slips off the tuber. Then place them in a cup or glass with a couple of inches of water to soak. Within a few days you should see some roots. Then you can plant them into pots or in the ground. Sweet potatoes like rich soil. Add plenty of compost to your soil. If you are using the horse manure make sure that it is aged properly and doesn't contain any fresh manure.

Hi, Jannis, Harvesting a few sweet potato leaves and young shoots for cooking should not harm the plant; just do not take too much. How much is too much? That should depend on the size and health of the plant. Some growers harvest the tips of the plants—the newest leaves on the end of a vine—and combine those with a few other things from the garden for stir fry or salads.
