After I planted some spring mix lettuce a couple of years ago, nothing survived except for this plant. It doesn't look like any of the leaves that I am used to. Does anyone know what it is? Is it edible? I am located in East Tennessee.
Thank you for any help you can give!
I just posted some more photos with measurements. The total length from base of the plant to the end of the leaf is about one foot. These plants have no flower growing from the base, however there is a separate plant nearby in the mix that does have flowers. I included a photo of it in case it is related. The original plant in question has leaves that are mostly smooth (some have tiny white or clear hairs on the backside or stem...some are smooth). They are almost as thick as spinach leaves.
