The white buds are eyes, where the new shoots will grow.

If the peonies have just been planted that year, it is recommended that you place a 2 or 3" (5 - 8 cm) thick layer of leaf or straw mulch over the plant, after the ground freezes. Remove this mulch in mid-spring.

Once you plant them keep an eye on them and make sure the frost does not heave them out of the ground. New peonies are susceptible to frost heaving as they do not have their feeder roots to hold them in place. Any peonies heaved out of the ground should be put back to their original location. If it is too frozen to do so they can be covered in place with soil until the ground thaws or taken in and placed in peat moss in the refrigerator until the ground thaws enough to dig.
