Connoisseur Plants – 1995

Connoisseur Plants are rare, new plants or hard to find old favorites, and they are part of the annual appeal and membership drive to benefit the Arboretum's many fine programs and its day-to-day operational expenses. These wonderful plants were sent to those who joined the Friends of JC Raulston Arboretum in 1995 and in December of the previous year at certain higher membership levels.

In 1995, we offered a total of 44 taxa from which our members were able to choose! These plants are no longer available.
