SCCS., 1964, Camellia Nomenclature, p.121: Medium pink with darker pink edge. Medium, upright growth. Blooms mid-season. Originated by A. Krueger, San Gabriel, California, USA. Received the William E. Wylam Miniature Award, 1974. See p.121, Macoboy, 1981, The Colour Dictionary of Camellias. Note: The 1964 and 1966 issues of Camellia Nomenclature both give this as a pink with a darker pink edge. However from the 1968 issue and on, the description was changed to pink with a white edge, and this is the form that currently carries the name “Tom Thumb”. From this it would appear that the sport “Thumbellina” was originally named “Tom Thumb”. Due to the present universal use of the name Tom Thumb for the white edged form and Thumbellina for the dark pink edged form, these are let stand. Sports: Thumbellina, Tom Thumb Blush. This cultivar was awarded  as an AGM (Award of Garden Merit) plant by the Royal Horticultural Society in 2002 at H5 rate (hardy: cold winter; -15°C to -10°C).
