Connoisseur Plants

Connoisseur Plants are rare, new plants, or hard-to-find old favorites. These wonderful plants are being offered to our donors.

Please note that several plants are available in very limited quantities. For some plants, we don't know the full range of hardiness, only how it has behaved at the JC Raulston Arboretum. Sometimes, we cannot find any information in our references on a particular taxon. This does not mean that the plant doesn't exist, perhaps just that we are staying one step ahead of published information. One of the purposes of the Arboretum is to test new plants for suitability to the southeastern United States. By growing some of these "new-to-us" plants in your own garden, you can be a part of this evaluation process. Feedback from you is invaluable!

Happy choosing, and thank you for your continued and invaluable support of the JC Raulston Arboretum.

Note: The distribution year listed below is the year the plants were awarded. Members request them early the following year. Ands they're picked up or delivered shortly thereafter.
