The irises in my area that do not thrive in heat are the Miniature Dwarf Bearded irises - the tiny ones. Some do not seem to mind, perhaps ones hybridized in this climate, while others just linger and diminish. This winter was unusually mild so I do not expect much bloom on some of them. I have not lost any of the little ones so far but I have several that have never bloomed. I am thinking of putting those particular ones in a rock garden and just letting them fend for themselves. I may enjoy ones more that responds to babying and will reward me with a little flower.
