Nancy Kendall, left, of Auburn and Linda Ashworth and Lisa Chasse, both of Lewiston, sort potted chrysanthemums at Farmer Whiting’s in Auburn on Thursday. “They are very much a fall flower,” Kendall said of the popular perennial. About 6,500 mums were planted the first week in May, said farm co-owner Buster Whiting. The farm’s mum patch will stay in bloom through the end of October.
