Perennial vegetables are vegetables that can live for more than two years.
Some well known perennial vegetables from the temperate regions of the world include asparagus, artichoke and rhubarb. In the tropics, cassava and taro are grown as vegetables, and these plants can live many years. Some perennial plants are cultivated as annuals in order to minimise pest pressure (e.g., potato, Solanum tuberosum).
Perennial vegetables are an integral part of many cultural diets around the world, particularly in tropical agriculture. In contrast, temperate Eurasian cultures have relied on annual cereals (oats, barley, wheat) as dietary staples since antiquity. [1] [2] Some examples of older temperate varieties include: seakale, skirret, sorrel, and Good King Henry.
Sorrel, also called common sorrel or garden sorrel, is a perennial herbaceous plant in the family Polygonaceae. Other names for sorrel include spinach dock and narrow-leaved dock.
The following outline is provided as an overview of and topical guide to sustainable agriculture:
Root vegetables are underground plant parts eaten by humans as food. In agricultural and culinary terminology, the term applies to true roots such as taproots and tuberous roots as well as non-roots such as bulbs, corms, rhizomes, and stem tubers.
Trinidad and Tobago has a unique history and its food is influenced by Indian-South Asian, West African, Creole, European, American, Chinese, Amerindian, and Latin American culinary styles. Trinidadian and Tobagonian food is dominated by a wide selection of dishes, most notably, doubles, roti, pelau, callaloo and curried crab and dumplings. Trinidad and Tobago is also known for its prepared provisions, such as dasheen, sweet potato, eddoes, cassava, yam, soups and stews, also known as blue food across the country. Corresponding to the Blue Food Day event held annually in Trinidad and Tobago.
Northern root-knot nematode is a species of vegetable pathogens which produces tiny galls on around 550 crop and weed species. They invade root tissue after birth. Females are able to lay up to 1,000 eggs at a time in a large egg mass. By surviving harsh winters, they can survive in cold climates.
Leaf vegetables, also called leafy greens, pot herbs, vegetable greens, or simply greens, are plant leaves eaten as a vegetable, sometimes accompanied by tender petioles and shoots. Leaf vegetables eaten raw in a salad can be called salad greens.
Taro is a root vegetable. It is the most widely cultivated species of several plants in the family Araceae that are used as vegetables for their corms, leaves, stems and petioles. Taro corms are a food staple in African, Oceanic, East Asian, Southeast Asian and South Asian cultures. Taro is believed to be one of the earliest cultivated plants.
Edible flowers are flowers that can be consumed safely. Flowers may be eaten as vegetables as a main part of a meal, or may be used as herbs. Flowers are part of many regional cuisines, including Asian, European, and Middle Eastern cuisines.
Verticillium wilt is a wilt disease affecting over 350 species of eudicot plants. It is caused by six species of Verticillium fungi: V. dahliae, V. albo-atrum, V. longisporum, V. nubilum, V. theobromae and V. tricorpus. Many economically important plants are susceptible including cotton, tomatoes, potatoes, oilseed rape, eggplants, peppers and ornamentals, as well as others in natural vegetation communities. Many eudicot species and cultivars are resistant to the disease and all monocots, gymnosperms and ferns are immune.
A crop wild relative (CWR) is a wild plant closely related to a domesticated plant. It may be a wild ancestor of the domesticated (cultivated) plant or another closely related taxon.
Fijian cuisine has long consisted of primarily foraged and farm-grown food. Although rice, wheat, and tea all became staples during Fiji's colonial era, native Fijians still eat primarily tubers and coconuts. The cuisine of Fiji is known for its seafood and various green vegetables, including ''ota'', a young forest fern, and ''bele'', a plant that resembles spinach.
Niue is an island in the Southern Pacific, mostly inhabited by Polynesians. The plantations are mostly filled with manioc, taro and breadfruit, but banana trees can be found. The wide range of exotic plants in Niue includes taros, pawpaw, coconuts, bananas, yams, cassavas and breadfruits: All are intensively used in the local cuisine.
Lūʻau, Luʻau, Laulau, Lū, Rourou, Rukau, Fāfā, Hāhā, and Palusami are all related dishes found throughout Polynesia based on the use of taro leaves as a primary ingredient. While taro generally is known as a root vegetable for its starchy corms, the leaves are consumed as well. The base recipe is vegetarian. Most often, coconut milk was added, and later meat or seafood. The texture of the dish range from a thick soup to a dense cake.
French Guianan cuisine or Guianan cuisine is a mixture of Creole, Bushinengue, and indigenous cuisines, supplemented by influences from the cuisines of more recent immigrant groups. Common ingredients include cassava, smoked fish, and smoked chicken. Creole restaurants may be found alongside Chinese restaurants in major cities such as Cayenne, Kourou and Saint-Laurent-du-Maroni.
