Iris tectorum 'Alba' is a prized selection of the Chinese roof iris...no, it's not from Japan despite rumors to that effect. The slowly spreading clump is composed of wide light green foliage. In mid-April and well into May in NC, the easy-to-grow clumps are topped with frilly white flowers held above the foliage. I. tectorum 'Alba' thrives both in dry shade and on damp roofs...anywhere as long as the drainage is good.
