The University Of Toronto President's Estate is a , 32 room residence for the University of Toronto's president located in the neighbourhood of Rosedale in Toronto, Ontario, Canada. The property overlooks the Park Drive Reservation Ravine formed by Yellow Creek and goes from Highland Avenue halfway down to the floor of the ravine. The house was built between 1908 and 1910 by Toronto architects Wickson and Gregg It was the home of gold-mining magnate David Dunlap and his philanthropist wife, Jessie (who donated the David Dunlap Observatory to U of T in 1935 in honour of her late husband). After Mrs. Dunlap's death (1946), the house went through one owner before being purchased in 1956 by U of T as a suitable residence for its president. ==Gardens and natural history== The upper lawn is bounded by mature ''Quercus'' and ''Acer saccharum'' on the north with a single mature specimen of ''Acer saccharinum'' and ''Ailanthus altissima'' next to the thirty two room estate house and a ''Robinia pseudoacacia'' on the Eastern edge of the half acre lawn.

Beneath a stone step lies the remains of a family pet whose name (Billy, 1947) is inscribed upon the stone. From here the second slope; peppered with ''Syringa vulgaris'' and stumps of trees and shrubs long gone, flows onto the third terrace where several varieties of ''Malus'' grow, along with ''Euonymus europaeus'', ''Sorbus aucuparea'' and ''Robinia pseudoacacia''. The greenhouses and grounds had been abandoned for six months except for some grass cutting by the University of Toronto Grounds Department in 1981 as the Estate Gardener had died that spring. It took the next Estate Gardener two weeks to get the two growing greenhouses and sheds up to working condition and it wasn't until September that the plants in the conservatory were transplanted, divided, cleaned and rejuvenated.〔Horticultural journals of Wayne Ray〕 File:93 Highland steps.jpg|Second tier steps 93 Highland File:93 Highland upper lawn beds.jpg|93 Highland upper lawn beds File:93 Highland rock garden.jpg|93 Highland rock garden with Mugho After the Fall season it was discovered that the lower of three tiers was in reality a half acre terraced rock garden with two large concrete ponds and a 300 foot artificial stream running to it from the east side of the upper lawn. The forest is composed primarily of ''Fagus sylvatica'', ''Quercus rubra'', ''Betula papirifera'', ''Acer rubrum'', ''A. saccharum'', ''Ostria'' and ''Robinia pseudoacacia''. The half acre rock garden encompasses the entire lower western section of the estate covering three smaller slopes and two smaller terraces.〔Horticultural journals of Wayne Ray〕 In the rock garden proper, including trees and shrubs, were found ''Tradiscantia virginiana'', ''Achillea lanulosa'', ''Pinus mugho'', ''Viburnum trilobum'', ''Acer palmatum'', ''Hieracium canadense'', ''Ulmus pumila'', ''Spirea vanhoutii'', ''Malus coronaria'', ''Asparagus filicina'', ''Robinia pseudoacacia'', ''Pteris'' spp., ''Potentilla recta'', ''Ranunculus acris'', ''Taxus cuspidata''`Hicksii', ''Chelidonium majus'' and ''Muscari botrides''. By 1982 many plants had germinated or been grown from cuttings and different species of plants. Only about 90 different species made it to adulthood from the greenhouse and cold frames. Nearly half of these new plants were being grown for the conservatory and the flowerbeds around the house. They included species of ''Begonia'', ''Fuchsia'', ''Pilea'', ''Euphorbia'', ''Peperomia'', ''Impatiens'', ''Hosta'' and other indoor plants.〔Windfield Photographic Collection and Archives〕 The University Administration was not overly interested in returning the President’s Estate to its earlier glory and especially not the rock garden as very few guests went to see it during university functions. By the end of 1983 the following wild flowers were successfully introduced the into the gardens; ''Aguiligia brevistilla'', ''Ranunculus abortius'', ''Lychnis chalcedonica'', ''Saxifraga aizoides'', ''Siline cotripacta'', ''Sedum anacampceros'', ''S. kamtshaticum'', ''S. kamtshaticum'' ''Oreo marginatum'', ''Malva sylvestris'', ''M. verticillata'', ''Potentilla tridentata'', ''Potentilla intermedia'', ''P. pentandra'', ''Polemonium corveleum'', ''Atriplex lentiformis'', ''Agastace foenicleum'', ''Campanula carpatica'' and ''Plantago lanceolata''. The President’s Estate is now looked after directly from the U of T’s Grounds Department and no longer maintains its own Estate Gardener.〔University of Toronto Archives〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「University Of Toronto President's Estate」の詳細全文を読む スポンサード リンク
