Evening light pulls out the rose in what appears as a deep violet. This 2011 Intro by Paul Black is 23" IB. Mid-America describes this cultivar:
Upright grape juice purple standards reveal red plum styles. Very round, palest pink white falls have dark red purple hafts changing to grape juice purple plicata bands. Short purple veins and sanding flank mid burnt orange beards ending in violet.
Here a clump of year two after planting a single rhizomes, shows 'Outer Edge' as great garden plant. Some fine show stalks are in there. It started blooming May 17 this year, peaked May 24 and bloomed until May 28.
