It is worth the effort to plant them with no eyes visible. I always do and have often had good plants result. Al

Most itoh peony roots will produce eyes pretty easily however with herbaceous roots, it still happens, but not as often. I would suggest digging it up, then potting it up in well drained soil to give it as much of a chance as possible. Adding azomite for the minerals, and some sort of fungicide should help it recover.

Its worth a try, you never know. Sometimes adventisous buds will develop from the energy stored in the tubers, Wait at least two years to see what happens from a normal planting. Al

Sorry to burst your bubble but the blooms were established last year. Some what convoluted explaination but bear with me. The roots have tissue in the crown area, top, that depending on chemicals released by the plant will form flower bearing stems or foliage. The growth of the tops provide nutrictian to the roots. Chemical exchanges triggered by light, temperature, and moisture tell the plant to start growing to open up the buds and expand. The tissue has been there since the root formed but the chemicals tell that part of the root to be either a root or a foliage stem. That chemical change normally happens during the summer before the bloom stalk grows. Therefore this years flowers were actually determined last summer. This is one of the reasons that many peony growers suggest that a feeding is best just after blooming. Don Hollingsworth does a much greater explaination. I have attached a photo of a peony root with eyes. The question that will pop into your mind is answered yes her roots are that large. Here is a link that might be useful: peony eyes
