Rodgersia is a genus of flowering plants in the Saxifragaceae family. Rodgersia are herbaceous perennials originating from east Asia.
The genus was designated by the American taxonomist, A.Gray, in 1885, who named it after the US Admiral, John Rodgers, commander of the expedition in which R. podophylla was discovered in the 1850s. By 1871, R. podophylla was present in the United States and was flowering in the Imperial Botanical Garden at Saint Petersburg and in 1878, seed brought back to a British nursery, Veitch & Sons, produced flowering plants.
R.aesculifolia was discovered by Father Armand David in 1869. R. pinnata, was also discovered by Abbé David, in China's Yunnan province, in 1883. It first flowered in the UK in 1902. R. sambucifolia was discovered by Ernest Wilson 1904 in Yalung, China.
R. nepalensis was not identified until in 1966 in the UK from a collection by Peter Schilling who made a second collection of seeds of this species . There are distinct differences between the plants raised from these two collections whose numbers are EMAK 713/901 and ED2879.
R. henrici which was initially thought to be an astilbe was collected by Prince Henri d'Orleans in 1895 but this has recently been reduced to a variety of R. aesculifolia.
In older literature there is mention of R. purdomii named after William Purdom who collected in China in around 1910. The herbarium specimen of a plant raised from that seed, at Kew, identifies it as R. aesculifolia.
