I have grown at least 25 varieties of Iris over the past 25 years, and Victoria Falls is one of my favorites. I'd rank it up there with the top 5.
I haven't had the problem with stem strength another reviewer mentions, though I have had other iris with that problem.
This is a striking shade of medium blue. The white beard and patch underneath it is a beautiful addition. Put it in a bouquet with iris that are a definite purple, and the illusion of true blue will be intensified.
Given proper maintenance, the plants have always been very healthy for us.

I realize that I am in the minority here, and I would never put a 'negative' because Victoria Falls now has finally bloomed in my garden; however, it has taken four years. The plant gets plenty of sun and has wonderful drainage. In terms of producing more fans, it is one of the fastest producers I have ever seen. It's just that no flowers have come from those fans until this year.
I do love the flower, though. A rich medium blue--almost delphinium blue shade with a very attractive, striking white beard and patch, as well as flush up the standards.

The joke in our region is "Victoria Falls, and she does". This one has a very nice flower, but is always on the ground here. Very lacking in stem strength.
This is an outstanding iris - color is clear and true, love that white beard - blooms every year and does not disappoint (z5). Great height too - 35" and taller, looks great with War Sails which blooms around the same time - great color contrast since both are clear and true colors.

Reliable rebloomer. As long as the plant is not overcrowded, the fall bloom is as good as the spring bloom.
