I "inherited" (meaning they were already there) a number of polyantha roses, probably "Margo Koster." Polyanthas are noted for sporting and "Margo Koster" in particular. Had 2 of them to start with and propagated 6 more from cuttings. The same shrub would often have 3 or 4 different colors of blooms, and also variations in the number of petals. Some simply doubles and others very densely packed with petals. Colors could range from nearly downright orange to wine red.

I did note that the dominant wine red shrubs did not sport as prolifically and any sports were variations on pink coral. No orange or orange coral. Was pretty neat.
