Sweet Potato Speciality Collection provides three reliable varieties with varied colour, flavour, and maturing times to make the most of your sweet potato crop. Sweet potatoes are normally grown from ‘slips’ which are long sprouts that have been removed from sweet potato tubers. However, these Sweet Potatoes are supplied as Super Plugs which are already well rooted and give you a head start on your sweet potato crop. Height and Spread: up to 3m (9').

Sweet Potato Speciality Collection comprises 18 plugs, 6 each of the following 3 varieties: 

  • Sweet Potato ‘Beauregard’ - a popular variety producing high yields of good-sized tubers with reddish purple skin and deep orange flesh.
  • Sweet Potato 'Bonita' – a variety with tan skin and creamy white flesh. High dry matter content makes it especially good for baking. Short cultivation time.
  • Sweet Potato 'Burgundy' – intense colour and flavour, with bright orange flesh and one of the sweetest.

How to Grow

Gradually acclimatise sweet potato plug plants to outdoor conditions over 7-10 days prior to planting directly outside once all risk of frost has passed. Sweet potatoes require high temperatures of 24-26°C (74-78°F). Planting them through black plastic will provide extra warmth in cooler climates. When growing sweet potato in particularly cold areas they are best grown in greenhouse borders or under cloches.

Plant sweet potatoes 30cm (12") apart, leaving 75cm (30") between rows. Grow sweet potatoes in rich fertile, light sandy well drained soil. They prefer an acid or neutral soil in full sun. Prepare the soil in early spring by adding plenty of well rotted manure or garden compost to the soil to improve its structure and fertility. Water generously after planting.

More Info
Water sweet potato plants regularly and hoe between plants to prevent weeds from establishing. Provide a thick mulch of organic matter around the base of the plants to help conserve moisture and reduce weed growth. Spread the stems out around the plant and cut back to the growing tips to encourage more lateral stems to develop. Harvest sweet potatoes in late summer approximately 12 to 16 weeks after planting, when the foliage begins to turn yellow and die back.

Culinary note: Culinary uses of sweet potato are similar to potatoes - boil, steam, bake, fry, mash or batter fry as 'tempura'. The leaves and tips of young shoots can be cooked as a spinach substitute.
