Edith Wolford has bloomed well in my Pacific Northwest garden for 8 years. It's a beautiful and unusual flower, yellow and blue. This iris multiplies quickly here, and I've given away a number of starts.

With Irises I have had rotting trouble in clay but they can survive. Edith Wolford is a nice flower. If you have clay soils amend a few inches with sand or course material to increase drainage and raise above surrounding grade. I now have a yard with deep topsoil that drains very well. However I still have rotting trouble when planted into the soil rather than on top.

Slow to grow for me with shorter than reported scapes. Perhaps I'll move it to a bit of late shade and more water. Good pod parent, but the pollen bugs have chosen this cultivar over all others to raid and I haven't beaten them to a single anther - every year all eaten off before the bloom opens even tried daily spray - so I haven't used it as a pollen parent.

This is a real stunner! One of my favorites -- the coloring is spectacular. Easy to grow, reliable bloomer. In years that we get plenty of rain, I've had this grow over 3 feet tall with huge blooms! Very showy. Highly recommended.

very reliable and blooms well with only 4 hours of direct sun. This iris is a perfect example of the perils of iris photography. The falls are blue but without a filter or a program that corrects color you get purple.
