Several years ago the septic field was planted smack in the middle of the wild Dwarf Crested Iris patch. Now it has more than doubled in size, I personally thought it would thin the patch dramatically. The patch used to be somewhere around 10' x 15' now it is like 15' x 30' and not quite as filled in as it was before the septic field. So we have 100s of blooms open and more coming tomorrow with our mid 80s temps. They only last a few days.
