History

Felicitas Svejda

Felicitas Svejda was born November 8, 1920, in Vienna, Austria. She studied agricultural science at the University of Natural Resources and Life Sciences in Vienna, where she earned a PhD in 1948. She moved to Canada in 1953 and was hired by the Canadian Department of Agriculture's research division in Ottawa, Ontario. Her first project was researching cereal grains, but later she began working with ornamental plants. Svejda was given a new project in 1961 to create a series of winter hardy roses which would thrive in the coldest regions of Canada, with sub-freezing winter temperatures of -50 C, and would also flower regularly during Canada's short growing season. [4]

With no prior knowledge of roses, Svejvda developed a successful rose-breeding program at the Central Experimental Farm (CEF) in Ottawa. [5] From the 1960s to the 1980s, she introduced many new cultivars, including 22 roses in the Explorer Rose Series, named in honour of Canadian explorers. Some of her most popular cultivars are 'John Cabot', 'Alexander MacKenzie', 'David Thompson', and 'Jens Munk'. [6] Svejvda led the rose-breeding program at CEF for 25 years until her retirement in 1985. Her roses continued to be introduced in Canada well into the 1990s. Svejda died on January 19, 2016, in Ottawa at the age of 95. [4]

'John Davis'

Svejda bred 'John Davis' by crossing 'Kordesii' and ('Red Dawn' x 'Suzanne'). The rose cultivar was introduced in Canada in 1977 by Agriculture and Agri-Food Canada. It is one of the Explorer Roses that Svejda developed to withstand the harsh Canadian winters and thrive in its short growing season. It has been described as the "most beautiful of the very hardy Canadian roses". [7] 'John Davis' is named for John Davis (1550–1605), an explorer and navigator who helped discover the Northwest Passage. He was also the first navigator to pass through the Davis Strait between Greenland and Canada. [2]

Garden roses Ornamental roses

Garden roses are predominantly hybrid roses that are grown as ornamental plants in private or public gardens. They are one of the most popular and widely cultivated groups of flowering plants, especially in temperate climates. An enormous number of garden cultivars have been produced, especially over the last two centuries, though roses have been known in the garden for millennia beforehand. While most garden roses are grown for their flowers, often in dedicated rose gardens, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedging.
