Autumn Mums bloomed too early, lol

We had these Autumn mums for 1 year now and we did not cut them back in the winter, so when the spring came they began to grow to its full height about 18 inches and they also started to bloom the beginning of July instead of the end of August or early September, never the less they are absolutely beautiful. We propagated about six more Mums and they should bloom in September. Autumn is my Mom's favorite season so I look forward to her Autumn landscaping ideals =)
