Connoisseur Plants

Connoisseur Plants are rare, new plants, or hard-to-find old favorites. These wonderful plants are being offered to our upper level members, Collector (formerly Sponsor) level and higher.

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.

To submit your selections, please use the form link in the e-mail you received on February 16, 2026 from Kathryn Wall. If you need assistance, please e-mail Kathryn at kbwall@ncsu.edu or call (919) 513-7004 Selections should be placed no later than end of day March 1, 2026.

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