No - unfortunately, I do not have room to expand the 9-ft. space. On one side is my patio, on the other is a cement sidewalk. So, what is currently planted in the first Iris garden is all that I can fit.
The second Iris garden space is shaped like an odd shaped semi-circle on the side of the house.
That also is at maximum capacity when it comes to iris rhizomes. There is no room to add any
more rhizomes there either. So, I do have some space on the other side of the house in the rock
garden to house maybe 4 rhizomes. The balance will have to be given away to neighbors who may want them for their own gardens.
Live and Learn ! I'll have to wait until next Spring
to see which rhizomes bloom and which do not.
