We obtained this extremely vigorous form of the winter blooming iris from the late Texas plant explorer Logan Calhoun, just before his death. It has been amazing in our garden with our 10-year-old clump spreading to 3' in width. The clumps are adorned from November through April (weather permitting) with fragrant blue-lavender flowers among the 30" tall foliage. We have found Iris unguicularis to grow best in well-drained soils where it gets a couple of hours of sun during the day.
