Kohlrabi is a biennial vegetable, a low, stout cultivar of wild cabbage. It is the same species as cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, savoy, and gai lan.
The sweet potato is a dicotyledonous plant that belongs to the bindweed or morning glory family, Convolvulaceae. Its large, starchy, sweet-tasting, tuberous roots are a root vegetable. The young leaves and shoots are sometimes eaten as greens. The sweet potato is only distantly related to the potato and does not belong to the nightshade family, Solanaceae, but both families belong to the same taxonomic order, the Solanales. The sweet potato is botanically very distinct from a genuine yam (Dioscorea), which is native to Africa and Asia and belongs to the monocot family Dioscoreaceae.
Nelumbo nucifera, also known as Indian lotus, sacred lotus, bean of India, Egyptian bean or simply lotus, is one of two extant species of aquatic plant in the family Nelumbonaceae. The Linnaean binomial Nelumbo nucifera is the currently recognized name for this species, which has been classified under the former names, Nelumbium speciosum Willd. and Nymphaea nelumbo, among others. This plant is an aquatic perennial. Under favorable circumstances its seeds may remain viable for many years, with the oldest recorded lotus germination being from that of seeds 1,300 years old recovered from a dry lakebed in northeastern China.
The rutabaga, swede, or neep is a root vegetable that originated as a cross between the cabbage and the turnip. The roots are prepared for human consumption in a variety of ways, and the leaves can be eaten as a leaf vegetable. The roots and tops are also used as winter feed for livestock, when they may be fed directly, or by allowing the animals to forage the plants in the field. Various European countries have a tradition of carving them into lanterns at Halloween.
Yam is the common name for some plant species in the genus Dioscorea that form edible tubers. Yams are perennial herbaceous vines cultivated for the consumption of their starchy tubers in many temperate and tropical world regions. The tubers themselves are also called "yams", having numerous cultivars and related species.
Cruciferous vegetables are vegetables of the family Brassicaceae with many genera, species, and cultivars being raised for food production such as cauliflower, cabbage, garden cress, bok choy, broccoli, Brussels sprouts and similar green leaf vegetables. The family takes its alternative name from the shape of their flowers, whose four petals resemble a cross.
Cooking bananas are banana cultivars in the genus Musa whose fruits are generally used in cooking. They may be eaten ripe or unripe and are generally starchy. Many cooking bananas are referred to as plantains (, ) or green bananas, although not all of them are true plantains. Bananas are treated as a starchy fruit with a relatively neutral flavour and soft texture when cooked. Bananas fruit all year round, making them a reliable all-season staple food.
A melon is any of various plants of the family Cucurbitaceae with sweet edible, fleshy fruit. The word "melon" can refer to either the plant or specifically to the fruit. Botanically, a melon is a kind of berry, specifically a "pepo". The word melon derives from Latin melopepo, which is the latinization of the Greek μηλοπέπων (mēlopepōn), meaning "melon", itself a compound of μῆλον (mēlon), "apple, treefruit " and πέπων (pepōn), amongst others "a kind of gourd or melon". Many different cultivars have been produced, particularly of cantaloupes.
Edible mushrooms are the fleshy and edible fruit bodies of several species of macrofungi. They can appear either below ground (hypogeous) or above ground (epigeous) where they may be picked by hand. Edibility may be defined by criteria that include absence of poisonous effects on humans and desirable taste and aroma.
