Iris tectorum 'China Blue' is a selection that we made from a population of wild collected Iris tectorum. We have been bowled over by both the size and vigor when compared to the Iris tectorum that is common in the trade. Each vigorous growing clump of wide green foliage reaches 18" tall x 2' wide. In April, the clumps are topped with spikes of dark blue-purple flowers on 2' tall flower stalks. This is a dramatic improvement over the typical species...both for gardens and roofs.
