I repotted some oriental stargazer lilies that had become pot bound.I divided and repotted some back into the pots and put other in ground. At the time of repotting I added new bagged composted soil.This summer they are blooming very differently. The flowers are more than double( about 10 extra petals).No visiable stamen. The petals are wavy. The colour is muted pale peach.What in heck @#$^& is going on?I hsve never had this happen.
