Rosa 'David Thompson' is a deep pink, Hybrid rugosa cultivar, bred by Canadian rose breeder, Felicitas Svejda in 1970. It was introduced in Canada in 1979 by Agriculture and Agri-Food Canada. It is one of the Canadian Explorer roses that Svejda developed and named in honour of legendary Canadian explorers.
'David Thompson' is a medium, bushy Hybrid rugosa rose, 3 to 4 ft (0.91–1.22 m) in height, with a 4 to 5 ft (1.2–1.5 m) spread. It has a double, cupped bloom form of medium sized 2.8 in (71 mm) flowers. Blooms vary in color from purplish-pink to deep red. Flowers often display streaks of white and the stamens are pale yellow. They are borne in short-stemmed clusters of 3 to 7. [2] The rose has a strong, sweet scent. The rose blooms in flushes throughout the season. It is a very hardy plant and is disease resistant. The leaves are small and medium green in colour, and have a tendency to turn brown at the edges. [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 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', 'Henry Kelsey', 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 Jan. 19, 2016 in Ottawa at the age 95. [4]
Svejda bred 'David Thompson' in 1970 using two Hybrid rugosas, 'Schneezwerg' x 'Fru Dagmar Hastrup'. [2] The rose cultivar was introduced in Canada in 1979 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. The rose was named for David Thompson (1770–1857), a British-Canadian fur trader, surveyor, and cartographer. [3]

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.
