Potato

Potato plants are herbaceous perennials that grow up to 1 metre (3.3 ft) high. The stems are hairy. The leaves have roughly four pairs of leaflets. The flowers range from white or pink to blue or purple; they are yellow at the centre, and are insect-pollinated.

The plant develops tubers to store nutrients. These are not roots but stems that form from thickened rhizomes at the tips of long thin stolons. The lenticels are circular and their number varies depending on the size of the tuber and environmental conditions. 

After flowering, potato plants produce small green fruits that resemble green cherry tomatoes, each containing about 300 very small seeds.

Onion

The onion is a biennial plant but is usually grown as an annual. Modern varieties typically grow to a height of 15 to 45 cm. They are fleshy, hollow, and cylindrical, with one flattened side. They are at their broadest about a quarter of the way up, beyond which they taper to blunt tips. The base of each leaf is a flattened, usually white sheath that grows out of the basal plate of a bulb. From the underside of the plate, a bundle of fibrous roots extends for a short way into the soil. As the onion matures, food reserves accumulate in the leaf bases, and the bulb of the onion swells.
