Centennial Sweet Potato Features:
Centennial is an older sweet potato variety that was developed by Louisiana State University in the 1960s. It has a 110 day maturity date but can stay in the ground longer if your weather conditions aren’t ideal for harvesting. Centennial is known for producing elongated sweet potatoes as opposed to the round sweet potatoes you’ll get from a variety like Georgia Jet.
Centennial sweet potatoes have an orange exterior and orange flesh. These longer sweet potatoes have a drier, more stringy texture than comparable orange sweet potato varieties. The longer shape makes Centennial a perfect variety for cutting into “chips” and frying.
Centennial Sweet Potato Growing Tips:
Sweet potato plants should be planted once soils have sufficiently warmed in spring or early summer. Due to their longer maturity date, our Centennial sweet potato plants are better suited for those living in the middle or southern states. We don’t recommend this variety for any gardeners north of Ohio.
Centennial is noted to perform well in heavier soils. As opposed to the traditional 10-12″ in-row plant spacing, we recommend a 14″ plant spacing with this variety. The plants need more room due to the shape of sweet potatoes they produce. Centennial sweet potato plants will also need at least 1″ of water per week for higher yields come harvest time.
