I think my favorite flower is the peony, but at this time of year before the peonies start blooming, I am always amazed at the variety of colors you can see on the irises in our neighborhood. Check out these examples and send me some of the ones from your neighborhood:
Bright yellow iris
This is a dark purple almost brown
This is a more typical color, the pale lavender/blue
This looks purple and white, but it is actually a pale blue color, this and the yellow are probably my favorites
This is a true white color, also beautiful.
What other colors have you seen? Burgundy red maybe?
