Rosa 'John Davis' is a pink Hybrid Kordesii rose cultivar, bred by Canadian rose breeder Felicitas Svejda. It was introduced in Canada in 1977 by Agriculture and Agri-Food Canada. It is considered to be best of the early Canadian Explorer roses that Svejda developed and named in honour of legendary Canadian explorers.
'John Davis' is a tall Hybrid Kordesii shrub rose variety, 7 ft (2.1 m) in height with a 6 ft (1.8 m) spread. [1] It has a quartered, cupped bloom form of medium-sized 3 in (76 mm) Flowers. Blooms begin as bright pink and then fade as they age to a lighter pink with golden centers. Flowers are carried in clusters of 10–15 and have a light, musky fragrance. [2] The rose will bloom occasionally during the season after its first flowering. The plant has an arching, rambling growth habit and glossy, dark green foliage. [3]
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]
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]
Rosa 'Sun Flare',, is a yellow floribunda rose cultivar, bred by William Warriner and introduced into United States by Jackson & Perkins in 1981. The rose won a gold medal in Japan in 1981, Portland in 1982 and was named an All-America Rose Selections winner in 1983.
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.
Felicitas Svejda was a federal scientist in Canada who developed roses that could survive Canada's short growing season and bitter winter conditions. She led the rose-breeding program at the Central Experimental Farm in Ottawa, Ontario, Canada for nearly 25 years. She developed the Explorer Rose Series named in honour of Canadian explorers. Many of her roses also thrive in Finland, Russia, Iceland, Germany and Austria.

Rosa 'Soleil d'Or' is a Foetida hybrid rose cultivar, bred by Joseph Pernet-Ducher and introduced on November 1, 1900.
