My irises went crazy this Spring! Very little care goes into this marvelous bed of irises. I inherited these lovely flowers from a friend who had become allergic to grass and leaves (almost anything outdoors) due to some medication she was on. She had about 300 irises. I didn't bring that many to my yard, but at least 100. Over the years they have died out, or the hybrid ones have reverted back to white. But the irises in this bed continue to hold their colors. It is such a great array of purples and violets.
The close-up here shows the various placements of the color in centers and the "falls" (the petals hanging down). Two of my favorites: 1) lavendar centers with purple falls; 2) purple/white centers with white falls outlined in purple.
The irises above that have not unfurled are white with lavender outlines in the centers and on the falls. Below is a close-up of one that has purple outlines and has unfurled.
Below is a photo of one of the lavendar ones as it begins to unfurl.
