I grow lots of Iris cristata selections and cultivars, wonderful plants for New England woodland gardens. A couple years ago, I added two white-flowered cultivars, 'Montrose White' and 'Precious Pearl'. To show just how different two "alba" forms can be, click on this landscape photo, on the left is the delicate 'Precious Pearl', on the right is the very large-flowered 'Montrose White'.



Iris cristata 'Precious Pearl' has flowers that are ever so slightly tinged blue, difficult to capture the color photographically. This is a 2013 Schmieder introduction.

When the flowers on 'Precious Pearl' first open, the buds more clearly show the slight blue infusion.

Iris cristata 'Montrose White' is a strong grower, with very large flowers of beautiful form, and brilliant yellow crests, perhaps the best white. Here, the flowers are just beginning to open.

These are lovely. My landscaper is putting in two new raised shade beds in an area that did not support lawn. I hope to put several varieties of iris cristata in one of them.
