It's funny you asked me that since my husband and I measured it a few wks ago thinking about adding some pavers/bricks of some sort for edging. We measured it from one fence post end to the other end and came up with 93 feet but didn't measure the other side yet that sits north & south.
I have around 86 varieties of Daylillies and some I have multiples of some and more in back of the house and all are labeled! "thank goodness" I do have other perennials within the Daylillies as well. I tell ya, I sure don't enjoy weeding the beds!
