Orchid or orchard?

They look a lot like the tubers of gloriosa lilies to me, but I'm betting the county extension people are more knowledgable than I...

Carolb, that's the first thing I thought when I saw them, too (gloriosa lily tubers). Can't tell for certain from the photo if the leaf structure matches or not, but it don't seem like it does.

If they were found along a fence line, it is possible that a prior owner planted gloriosa lilies, as they have tendrils and like to climb.

Yep, gloriosa tubers. They are going dormant right now, so have no foliage. Plant them somewhere they can climb, and you will be rewarded with beautiful flowers in the summer.

Was this a spot you'd always kept mowed before? When drought made our grass go dormant a couple years ago, I found Lycoris and Gladiolus bulbs in the lawn. They were still green, and had just been getting mowed along with the grass for many years. I dug up and moved as many as I could and have started getting some blooms this year.
