First year in Virginia
I had the good fortune to obtain iris from my sister in Indiana who had iris from our Mom's garden going back to the early 1950s. I planted these last June, about 80 Rhizomes, sharing some others with my son. Most of his were purple.
I intended to mark each plant with a small wood stick and cross reference with a photo album so that in the future when it is time to divide them, I can bring those of the same together.
Having fun going through iris catalogs trying to learn more of what I have.
