Potatoes are one of the most used vegetables around the world. This vegetable is grown from stem cuttings called seed pieces or seed eyes. They are really a potato that contains a couple of eyes where the new growth sprouts from.

This vegetable takes up a lot of space for the amount of harvest you will get, so if you want to have enough to store for the winter you will need a large plot.

Botanical Family - Solanaceae/Nightshade Family

Location - Sunny, well drained, moist. Thrive in mild, cloudy weather.
