Wildwood Garden, Bilpin, NSW Australia.
Iochromas are a group of fast-growing, South American shrubs. The name is derived firstly from ‘io’, from the word ‘iodine’, because the first species discovered was the deep blue-purple colour of iodine; and secondly from ‘chroma’ as in ‘colour’. There are about 24 species of Iochroma but not many of them are in cultivation. This is Iochroma Grandiflora.
