Iris tectorum 'Slippery Slope' is an amazingly vigorous roof iris introduced by Darrell Probst, which he found in Sichuan, China. For us, Iris tectorum 'Slippery Slope' forms the largest clump of any Iris tectorum we've seen, forming a 30" wide, tight-clustering clump in 3 years topped, starting in late April, with 2' tall spikes terminating in lovely blue-purple, six-petalled flowers. The three falls (horizontal to pendent) petals are adorned with a lovely white eyezone etched with purple lines.
