I collect cultivars of our native crested iris, Iris cristata. One of my favorite of two large-flowered selections is 'Eco Orchid Giant' selected and named by the late Don Jacobs, I believe a wild selection from Georgia. Flowers are very large and hold themselves up better than 'Powder Blue Giant'. Extremely hardy, I'm always amazed that the rhizomes romp around above the soil surface and root where they touch down. Several views of plants in flower from early to mid may,
