A pineapple pit is a method of growing pineapples in colder climates. One of the earliest examples in Britain has been found by archaeologists at Heligan in Cornwall. [1] The first pineapples known to have been grown in Europe were cultivated in the Netherlands. [2] None were grown in England until about 1715. [3]
The pineapple pit consisted of three trenches covered with glass, slightly below ground level, connected with two cavity walls. The outer troughs were kept filled with 15 tonnes of fresh horse manure, which gave off heat as it decomposed. This heat passed through small gaps at the bottom of the wall, rose up, and was then forced through gaps at the top of the wall, into the central trough. The central trough is where the pineapples were grown, at an artificially high temperature, due to the manure.
A pineapple pit requires a huge amount of fresh manure, and manual labour to maintain the temperature of the central trench. The introduction of steam ships meant that the pineapple pit became obsolete, as it was cheaper to transport fruit from overseas than to grow them under special conditions in the UK.
An original pineapple pit was discovered at the Lost Gardens of Heligan in the UK, and renovated in 1993 by John Nelson, architectural historian John Chamberlain, and horticultural historian Peter Thoday. [1] The original design was by Thomas Andrew Knight FRS. [4] It uses two varieties of South African pineapples, Jamaica Queen and Smooth Cayenne. In 1997, the first pineapple was successfully grown in the renovated pit. The second pineapple grown there was presented to Queen Elizabeth II of the UK.
The pineapple is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae.
The Lost Gardens of Heligan are located near Mevagissey in Cornwall, England and are considered to be amongst the most popular in the UK. The gardens are typical of the 19th century Gardenesque style with areas of different character and in different design styles.
A greenhouse is a structure that allows people to regulate climatic conditions, such as temperature and humidity. There are many different designs of greenhouses; however, in general these buildings include large areas of transparent material to capture the light and heat of the sun. The three most common transparent materials used in the roof and walls of modern greenhouses are rigid plastics made of polycarbonate, plastic films made of polyethylene or glass panes. When the interior of a greenhouse is exposed to sunlight, the internal temperature rises and shelters the plants from cold weather.
Horticulture is the cultivation of plants in gardens or greenhouses, as opposed to the field-scale production of crops characteristic of agriculture. It includes the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. It also includes plant conservation, landscape restoration, landscape and garden design, construction, and maintenance, and arboriculture, ornamental trees and lawns.
Feijoa sellowiana also known as Acca sellowiana (O.Berg) Burret, is a species of flowering plant in the myrtle family, Myrtaceae. It is native to the highlands of southern Brazil, eastern Paraguay, Uruguay, northern Argentina, and Colombia. Feijoa are also common in gardens of New Zealand. It is widely cultivated as an ornamental tree and for its fruit. Common names include feijoa, pineapple guava and guavasteen, although it is not a true guava. It is an evergreen shrub or small tree, 1–7 metres (3.3–23.0 ft) in height.
Mangosteen, also known as the purple mangosteen, is a tropical evergreen tree with edible fruit native to tropical lands surrounding the Indian Ocean. Its origin is uncertain due to widespread prehistoric cultivation. It grows mainly in Southeast Asia, southwest India and other tropical areas such as Colombia and Puerto Rico, where the tree has been introduced.
The loquat is a large evergreen shrub or tree grown commercially for its orange fruit and for its leaves, which are used to make herbal tea. It is also cultivated as an ornamental plant.
Monstera deliciosa, the Swiss cheese plant or split-leaf philodendron is a species of flowering plant native to tropical forests of southern Mexico, south to Panama. It has been introduced to many tropical areas, and has become a mildly invasive species in Hawaii, Seychelles, Ascension Island and the Society Islands. It is very widely grown in temperate zones as a houseplant.
A polytunnel is a tunnel typically made from steel and covered in polyethylene, usually semi-circular, square or elongated in shape. The interior heats up because incoming solar radiation from the sun warms plants, soil, and other things inside the building faster than heat can escape the structure. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall. Temperature, humidity and ventilation can be controlled by equipment fixed in the polytunnel or by manual opening and closing of vents. Polytunnels are mainly used in temperate regions in similar ways to glass greenhouses and row covers. Besides the passive solar heating that every polytunnel provides, every variation of auxiliary heating is represented in current practice. The nesting of row covers and low tunnels inside high tunnels is also common.
Grevillea, commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus Grevillea are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds.
A walled garden is a garden enclosed by high walls, especially when this is done for horticultural rather than security purposes, although originally all gardens may have been enclosed for protection from animal or human intruders. In temperate climates, especially colder areas, such as Scotland, the essential function of the walling of a garden is to shelter the garden from wind and frost, though it may also serve a decorative purpose. Kitchen gardens were very often walled, which segregated them socially, allowing the gardeners, who were usually expected to vanish from the “pleasure gardens” when the occupants of the house were likely to be about, to continue their work. The walls, which were sometimes heated, also carried fruit trees trained as espaliers.
Thomas Andrew Knight (1759–1838), FRS, of Elton Hall in the parish of Elton in Herefordshire and later of Downton Castle, was a British horticulturalist and botanist. He served as the 2nd President of the Royal Horticultural Society (1811–1838).
The Dunmore Pineapple is a folly in Dunmore Park, near Airth in Stirlingshire, Scotland. In 1995 it was ranked "as the most bizarre building in Scotland".
Phoenix canariensis, the Canary Island date palm or pineapple palm, is a species of flowering plant in the palm family Arecaceae, native to the Canary Islands off the coast of Morocco. It is a relative of Phoenix dactylifera, the true date palm. It is the natural symbol of the Canary Islands, together with the canary Serinus canaria. Mature P. canariensis are often used in ornamental landscaping and are collected and transplanted to their new planting location. A Canary Island date palm with 10 m (30 ft) of trunk is approximately 60 years of age.
An orange is a fruit of various citrus species in the family Rutaceae ; it primarily refers to Citrus × sinensis, which is also called sweet orange, to distinguish it from the related Citrus × aurantium, referred to as bitter orange. The sweet orange reproduces asexually ; varieties of the sweet orange arise through mutations.
The Heligan estate was the ancestral home of the Tremayne family near Mevagissey in Cornwall, England. Purchased by Sampson Tremayne in 1569, the present house was built in 1692 and extended in the early 19th century. The family left the house after World War I, and by the end of World War II the house and gardens had fallen into disrepair. The house and outbuilding were converted into flats in the 1970s and the garden was considered lost, but it was rescued during a televised project in 1996. The Lost Gardens of Heligan are now open to the public as a tourist attraction.
The Potager du roi, near the Palace of Versailles, produced fresh vegetables and fruits for the table of the court of Louis XIV. It was created between 1678 and 1683 by Jean-Baptiste de La Quintinie, the director of the royal fruit and vegetable gardens. Today it is run by the École nationale supérieure du paysage, the grande école for landscape architects. It is officially recognized as a Remarkable Garden of France.
The fig is the edible fruit of Ficus carica, a species of small tree in the flowering plant family Moraceae, native to the Mediterranean region, together with western and southern Asia. It has been cultivated since ancient times and is now widely grown throughout the world. Ficus carica is the type species of the genus Ficus, containing over 800 tropical and subtropical plant species.
A walipini is an earth-sheltered cold frame. It derives its name from the Aymaran languages. It is similar in concept to the pineapple pit that was used, as the name implies, to cultivate pineapple and other exotic fruits in Victorian era Britain and in the cold plains of pre-revolution Russia.
Forcing is the horticultural practice of bringing a cultivated plant into active growth outside of its natural growing season. Plants do not produce new growth or flowers during the winter, and many species only produce flowers or fruit for a very limited period. Forcing allows horticulturalists to produce these flowers and fruits at other times. This can be accomplished by cultural, physical, or chemical means, and is typically done to produce out-of-season flowers or fruit for display, consumption or sale. Forcing allows the more predictable production of products for sale, and can improve the quality of the products in some cases.
