re-ordered from within their existing landscape, Persian gardens appeared as impossibilities. Their ethereal and delicate qualities emphasized their intrinsic contrast to the hostile environment. Trees and trellises largely feature as biotic shade; pavilions and walls are also structurally prominent in blocking the sun. The heat also makes water important, both in the design and maintenance of the garden. Irrigation may be required, and may be provided via a form of tunnel called a qanat, that transports water from a local aquifer. Well-like structures then connect to the qanat, enabling the drawing of water. Alternatively, an animal-driven Persian well would draw water to the surface. Such wheel systems also moved water around surface water systems, such as those in the chahar bāgh style. Trees were often planted in a ditch called a juy, which prevented water evaporation and allowed the water quick access to the tree roots. The Persian style often attempts to integrate indoors with outdoors through the connection of a surrounding garden with an inner courtyard. Designers often place architectural elements such as vaulted arches between the outer and interior areas to open up the divide between them. Egyptian gardens Gardens were much cherished in the Egyptian times and were kept both for secular purposes and attached to temple compounds. Gardens in private homes and villas before the New Kingdom were mostly used for growing vegetables and located close to a canal or the river. However, in the New Kingdom they were often surrounded by walls and their purpose incorporated pleasure and beauty besides utility. Garden produce made out an important part of foodstuff but flowers were also cultivated for use in garlands to wear at festive occasions and for medicinal purposes. While the poor kept a patch for growing vegetables, the rich people could afford gardens lined with sheltering trees and decorative pools with fish and waterfowl. There could be wooden structures forming pergolas to support vines of grapes from which raisins and wine were produced. There could even be elaborate stone kiosks for ornamental reasons, with decorative statues. Temple gardens had plots for cultivating special vegetables, plants or herbs considered sacred to a certain deity and which were required in rituals and offerings like lettuce to Min. Sacred groves and ornamental trees were planted in front of or near both cult temples and mortuary temples. As temples were representations of heaven and built as the actual home
