Caladium × hortulanum
'John Reed' & 'Frieda Hemple'

IMHO, both cultivars are identical, also 'Florida New Release' doesn't differ from them.

Two photos from Bloemenbureau Holland catalogues. They were presented without names.
'John Reed' (written in the book).	A photo taken by myself ensured me that 'J. Reed' and 'F. Hemple' are the same cultivar.
