NAVAJO BLUE: (O. D. Niswonger, R. 2001). Sdlg. 20-96. TB 38" (97 cm) M. "Light blue, F. with darker blue around hafts, hint of turquoise; beards pale blue base and at end, gold hair tips and gold in throat. 34-94: (Charm City Choice x Timescape) X Just Magic., Cape Iris 2001." I'm glad to see such a beautiful iris from the Midwest (Cape Iris Gardens, MO)! Mr. Niswonger is also the originator of many great irises, including the Dykes Metal Winner 'Everything Plus'; 'Brown Lasso' Dykes Metal 1981; a great orange 'Tennessee Vol', and 'Apricot Frosty' Knowlton Metal 2000. This one grows very rapid here; making a large 18" clump in just two years! Great color; hardy and very nice!

Gorgeous coloring, and beautifully formed flowers. A very nice mid-season bloomer, but fell far short of it's AIS registration 38" height. A slow grower and sporadic bloomer in my garden, but definately a keeper !!!
