'Silver Edge' Siberian Iris is the most robust Siberian I have. If given adequate water, flower stems will reach nearly 4 feet. The flowers are also quite large for this group. The faint white edge to the deep violet-blue flowers is a real knockout. As a cutflower, they are second to none.

The flowers of 'Silver Edge' are among the largest of Siberian Iris. The delicate white edge is a lovely contrast to the mid-blue flowers.
