Camellia japonica
As well as 'Prince Frederick William', Silas Sheather also developed the cultivar "Camellia japonica" 'Harriet Beecher Sheather' (1872), named after his daughter. Both of these cultivars are still commercially available. Other camellia cultivars developed by Sheather were 'Astarte', 'Minnie Warren', 'Mrs. Dellissa', 'Sheatheri' and 'St. George'.
