Iris reticulata in mild winters
I stopped at OSH to pick up a pot, and happened to pass by their new display of bulbs. I bought a package labeled Iris 'Reticulata'. The package shows them growing in a pot and says they reach 6 inches tall, so these must be the species, I. reticulata.
My trusty Sunset Western Garden Book says I. reticulata blooms mid-winter in mild areas (like mine) and "need some subfreezing winter temperatures to thrive". Great! So, unless our winter temps get below 32F, they won't thrive.
Do any of you in mild-winter zones successfully grow this Iris? Should I store it in the freezer and plant it in spring? Or plant them once in a container and toss them after they bloom?
