My order invoice from Maryott's last fall was dated 9-03-13, which is probably when they sent them out. They are all full healthy plants with buds. They were large when they were planted, also, so maybe where they are coming from makes a difference? A fan from the north that hasn't had as much growing time may not do as well as one from the south or California?
My other DL's were ordered in July. I never have as much enthusiasm for ordering plants in February as I do when they start to bloom. Sometimes I don't even open my garden mags and catalogs over the winter!
