A friend is asking me about a problem with a young peony and I told her I'd ask the experts. I thank you in advance.

She planted three peony "eyes" last fall that were purchased at a nearby bulb grower. They are planted within 4 feet of one another. Soil is good...other plants in the bed do well. The bed gets afternoon shade. One plant looks great...about a foot tall, dark green leaves and healthy looking. The second one looks normal except the color is more yellow green. The third one doesn't look normal at all. It's about 8 inches tall, with very small, elongated leaves that are curled from one side of the leaf to the other...sort of like a boat shape. This particular little plant has been shaded by some poppies this spring, but those are coming out. Could it be because it hasn't had enough sun? Can anyone give me any idea of what may be going on...especially with the most abnormal plant? Thanks!
