Potatoes are easy to grow; unlike other crops, they do not require large amounts of fertilizer or chemical additives and use less water than other crops. Potatoes are grown as annual plants. Depending on the climate, potatoes are planted and harvested at different times of the year. For example, in the northern United States, fields are typically planted in the spring and harvested in the fall. The part called a “potato” grows underground. The potato grows on a specialized underground stem called a stolon. So, although potatoes grow underground, they are stems, not roots, and are known as “tubers.” Potato flowers tell you that the plant is starting to produce the tubers we grow them for under the soil. Flowers on the potato plant bloom towards the end of their growing season. A potato plant grows almost 60 centimeters or 24 inches in length. They grow at the height of 4,000 meters above sea level. The plants bloom in different colored flowers like white, blue, purple, red, and pink. The color correlates to the type of potato that is growing. Red flowers mean it is a red potato plant.
