The first phase is where the seed potatoes develop sprouts. ![]() ![]() But when developing new varieties, the seeds from the fruits are used. You can develop these seed potatoes yourself or buy treated ones from a certified supplier. You grow potatoes from seed potatoes, which are the tubers kept for some time until they develop some sprouts. But if you expose the potatoes to too much sunlight, the toxic levels could rise to a point where they are harmful to humans. Glycoalkaloids offer protection against sunlight and pests. However, the tubers also contain toxic glycoalkaloids, but in small amounts. The only part that’s safe to eat is the tubers. The fruits, leaves, and stems contain alkaloid solanine which is toxic to humans. Once the potato plant matures, the leaves die (turn to a brownish color), and the flowers turn to fruits. The flowers can be white, blue, red or pink, but they all have yellow stamens. Potatoes are generally herbaceous, with stems that grow up to 24 inches in height, green leaves, and flowers.

They are believed to have originated in Peru, South America, before they spread to other parts of the World. Potatoes are perennial vegetables whose cultivation dates back up to 10,000 years ago. Keep reading to find out more about potatoes and what makes them tubers.īefore we discuss how tubers work, let’s first take a brief look at what the potato is and how potatoes grow. Tubers develop from an underground stem known as a stolon, and they act as storage for food/starch for later use by the plant. Potato is definitely not a root, and it’s not really a stem. So which one is it? Is potato a root or a stem? Well, we can’t blame anyone who thinks so since most of the things that grow underground are roots. ![]() Most people assume that potatoes are roots because they grow underground.
