@rockyrose1, I have purchased a number of plants from Roberta's over the years and the only losses or problems I've had was due to "operator error" not the plants.
I have also given Roberta's plants as gifts and the recipients have been very happy with the plants.
In addition to their own line on Q they also provide plants to Phillip Watson's and Carolyn Gracie's lines.
I agree that buyers are more inclined to take the time to post complaint reviews but take into consideration the number of years Roberta's has been on Q and how much their offerings have expanded.
If the majority of buyers were unhappy Roberta's would not be on Q for 20+ years.
I hope you will be as happy with your plants as I've been with mine.
The eyes through which you see others may be the same as how they see you.
