Tripple Brook shipped my plants in July, which being the hottest month of the year is not so good for transplanting. (Their catalog mentions that they ship "later" than other companies but I certainly wasn't expecting things THAT late.)
Also the wintergreen plants were flowering on arrival, it is my understanding that it is extremely hard on a plant to be transplanted while in bloom!
Since I was unemployed when the plants arrived, I was able to devote the next month to keeping them from dying. Now that I am back to work, I would not consider ordering from Tripple Brook again since I won't have time to spend all day every day preventing the plants from becoming too hot or dry in July and August.
