Unfortunately, I do not have the space or the garden size to spread out clumps that far apart
My one Iris garden is a rectangle - It is 9-ft. long by 2 1/2-ft wide. I don't know how many "Triangles"
I'll be able to plant in the space. I already have some iris rhizomes already planted in that space.
But I will do my best. Thanks for the recommendations.
