Its that time of year-Cosco Bulbs/Louisian Iris

andres_zone3March 22, 2010

I was in Cosco today and saw a variety of Louisiana Irises for sale. I couldnt believe how many different types they had. Anyways I got myself a bag of a deep wine-coloured L. Iris called Rhett. Does anyone know if you plant iris rhizomes in the spring, would you get blooms in the summer.???? Ive been reaserching Louisiana Iris's hardiness throughout the web and find reports saying they are only hardy to zone 6a and others that say zone 4. Any thoughts??
