Plant Details: Giant Blue Flag Iris
5 - 10
Giant Blue Flag Iris
This is no ordinary Blue Flag Iris. 'Tetra' has four times as many chromosomes as the species. This characteristic is shown with huge flowers for the species as well as the rapid growth, which allows it to fill an 4'x 4' area with in a year. The foliage can stand 3'+ High in spring then as it matures in late spring the tips gracefully arches over and remain that way all summer in to fall. The vigor of 'Tetra' is matched by no other selection and it alone is reason enough to this selection in your garden. Great for erosion control as many other Native Water Iris species are.
