@MarilynK - I LOVED that garden!!! Still had their catalog up till about a year ago a reference guide...LOL Are you looking for 4"-6" potted tropicals that you'd have to bring indoors come fall or larger plants? There are a few mail order places that I love because of their fair prices and healthy plants:
Pepper's Greenhouses (they also have a brick and mortar locale): 13034 Cedar Creek Rd, Milton, DE 19968 Phone: (302) 684-8092
http://www.accentsforhomeandga... Excellent selection of 4" potted tropicals.
Nurseries Caroliniana:
http://www.nurcar.com/ Shipping is a bit but they send gorgeous healthy good sized plants
Almost Eden:
https://almostedenplants.com/ Great selections - amazing packing - robust/healthy plants.
Lastly...although truthfully it's been quite a few years since I placed an order...
Zone 9 Tropicals:

Course you always have Logees but I find them higher priced than the others given equal sizes. They do have an amazing selection though.
