Sweet Potato Paradise Tahiti - Ipomoea batatas

Ipomoea batatas Paradise 'Tahiti' is part of a new unique series called "Paradise", combining ornamental foliage with edible tuber production. It is the result of extensive research conducted at Louisiana State University (LSU), a specialist in sweet potato hybridisation. Five new varieties have been created, including 'Tahiti', which has elegantly cut, dark green leaves with purple veins and produces edible tubers with purple flesh. This beautiful plant has a semi-trailing growth habit. It is perfect for decorating patios and balconies. Plant the plugs from April to June, after the last frosts. It works well in open ground, under cover, or in a pot, depending on the climate. Harvesting takes place from September to November.

Reaching only about 20cm (8in) tall, this perennial plant can spread up to 1.5m (5ft) wide in the ground with its long trailing stems. When grown in a pot, it will form a more modest clump, approximately 80cm (32in) wide. It belongs to the Convolvulaceae family and the Ipomoea genus. ‘Tahiti’ has highly decorative foliage but does not flower. It produces elongated tubers covered with orange to greyish skin, which protects the firm purple flesh that is high in starch and sugars. This exotic plant requires warmth and water to thrive. It can be planted in the ground in regions with hot summers. In cooler regions, grow it under cover or in pots.

On the balcony or terrace, 'Tahiti' can be used in pots, planters, or hanging baskets to create floral compositions. Combine it with other varieties from the Paradise series, blue, pink, or white lobelias, and red or bright pink pelargoniums, for example. It can also be planted with pink, orange, or red petunias and calibrachoas. It will form unique annual borders and ground cover, creating a lace-like backdrop for taller perennials. Its foliage is most beautiful when the plant is slightly shaded in the afternoon.

In terms of cooking, sweet potatoes can be prepared like regular potatoes (mashed, gratins, soups, sautéed, etc.). Their sweet taste also makes them suitable for use in desserts such as cakes, pies, and jams. The edible leaves can be consumed like spinach. Sweet potatoes are rich in beta-carotene, vitamin B6, and minerals (copper and manganese).

Harvesting: sweet potatoes are short-day plants. Tuber formation begins in September-October when the foliage turns yellow. Cut the foliage just before harvesting. Gently dig up the tubers with a garden fork, taking care not to damage them. Let them dry in the sun for a few hours. Harvesting should be completed before the first frosts.

Storage: sweet potatoes can be stored like regular potatoes. Keep them in a cool, dry place away from light.

Gardening tip: although the plant provides ground cover, mulch the soil to keep it moist and reduce weed growth, especially at the beginning of cultivation.

Please be aware that our young plug plants are professional products intended for experienced gardeners. Upon receipt, transplant and store them under cover (veranda, greenhouse, cold frame) at a temperature above 14°C (57.2°F) for a few weeks before planting outdoors once the risk of frost has passed.
