The Louisiana Iris Suite Images and reflections by Dick Sloan From The Heart Louisiana Hybridizers ![]() This is 'Cajundome' by Arny, in 1985. I love the contrast of the beetroot color with the brilliant gold signal. Charles Arny lived in Lafayette and his wife still lives there. He was the leading hybridizer of Louisianas for years, registering plants from the 1950's well into the 1980's. His 'Charlie's Michele', 1969, is regarded as bringing in the modern full formed, ruffled flowers. Any garden would look good today using the wide variety of colors included in his registrations. 'Creole Rhapsody', Mertzweiller 1998. Dr. Joe Mertzweiller
was an oil chemist from Baton Rouge and was the first to create
tetraploid Louisianas. Joe introduced a series of tetraploids,
all with the names 'Professor ______'. He also produced notable
diploids. He treated diploids with colchicine, a dangerous chemical
obtained from colchicum bulbs. These are autumn blooming flowers
somewhat like larger crocus blooms. The bulbs looksomewhat 'Creole Rhapsody' resulted from a cross of a diploid with a tetraploid. Joe called it an interploid. It hasn't been checked under a microscope to determine its ploidy. Marie Caillet bloomed a chance seedling which looked so like it, except in a different color shade, that she was sure it was a seedling from it. However, we are not sure it survived transplanting last year, and must wait another bloom season to decide.
'Freddie Boy' is a 1974 Mertzweiler introduction, in commerce for almost 30 years. To me, it still looks modern and I really like the two-tone color. Here, some years late spring cold weather aborts the bloom, but this is infrequent and most years its beauty makes me forget the few bad years.
'Starlite Starbrite' was registered in 1985. It is
one of the last of a line of doubles from Marvin Granger, of
Lake Charles, LA. He found a double bluish iris growing in a
swamp while on a collecting trip in the 1950's. From that, the
only wild double ever discovered, he produced 'Acadian'. Sidney Conger, a mortician, introduced a number of Louisianas during the 1950's and1960's. His most widely grown today is named 'Marie Caillet', a purple bitone registered in 1967, named when she selected it from seedlings. Marie has five named with some variation of her name, a mark of affection for her. Mr. Conger also registered one in 1957 named 'Segregation', which shows how attitudes were in those years and also that at least some progress has occurred since that time.
