We at the Q&A service do not have information as to shipping of various plants to Home Depot nurseries across the country. I suggest you contact your local Home Depot Garden Center manager to ask about when they will be able to get in the plants you are interested in.
The Sunpatiens are worth searching for and have performed very well in the trials at the Dallas Botanical Garden. You might also try calling the botanical garden to inquire as to where they can be purchased locally as the staff there may recall seeing them somewhere in the are for sale.
Thanks for the question. Please stop in again soon!
