Rosa 'Madame Caroline Testout' is a bright pink hybrid tea rose, bred by French rosarian, Joseph Pernet-Ducher.

They bred their new rose varieties using controlled pollination with great success and were able to create many popular new cultivars, including 'Madame Caroline Testout' (1890) and 'Mme Abel Chatenay' (1895).

It grew to be an exceptional floriferous rose with large blooms and a unique and beautiful blended color of pink, peach, yellow, and apricot.

[4][8] 'Mme Caroline Testout' was bred by Pernet-Ducher in 1890 by crossing the light pink tea roses, 'Madame de Tartas' and 'Lady Mary Fitzwilliam'.

The rose was named after Madame Caroline Testout, a late 19th-century French dressmaker from Grenoble, and the owner of fashionable salons in London and Paris.

It was very popular in both Europe and the United States, receiving wide acclaim for its floriferous and satiny, rose-pink flowers.

In Portland, Oregon in the early 1900s, 'Mme Caroline Testout' shrubs were planted in the hundreds of thousands along its city streets.
