Please do not get excited about growing lots of sweet potatoes in your garden as this variety has been cultivated for its it's dark purple to almost black arrow shaped foliage, not it's tubers. True, it will produce tubers but these are small, starchy, not at all sweet and although edible, once is usually enough. Sweet Caroline is very fast growing and is excellent for trailing over walls, hanging baskets or winding its way through other exotics in a tropical border. Not at all hardy so in early autumn, before the first frosts, cut back the foliage and lift the tubers. Store these in a ventilated container packed with only slightly damp compost in a dark, frost free place. Plant out again in late May the following year. It produces masses of sumptuous burgundy-purple leaves. The most likely variety to produce flowers. Any moist but well drained soil. Maximum height 15cm with a spread of several meters.
Sent as a young plant in a 9cm pot.
