Looks good to me. The poor rose is finally getting nice weather and is responding by putting out some nice canes.

It's odd growth for a KO, but not rosette disease. I wouldn't worry. If this growth pattern persists for months, it could be a mutation. There are certain polyantha roses that make basal foliage and tall, leafless flower clusters.

That's not RRD growth. It might be something weather related and left over from this bad winter and spring. I'd let them bloom and then cut those canes back and hope the plant grows out more evenly. Dead head those old blooms off the lower growth too. Dead heading and pruning will signal the plant to start growing again. Otherwise, they look pretty healthy. Good job!
