University of Arkansas Plant Evaluation Program
Dr. James Robbins and Dr. Jon Lindstrom
The University of Arkansas plant evaluation program was initiated in 1999
with the purpose of evaluating new or underutilized ornamental plants on a
statewide basis.
The program is unique among university programs in that it includes multiple
sites that represent three USDA cold hardiness zones. The program also differs
from many other programs in that it uses more than one plant at each test site
and collects quantitative data in addition to standard qualitative observations.
Plants are evaluated for five years and shrubs are never pruned. Information
collected from this program will be invaluable in selecting and marketing
ornamental plants adaptable to Arkansas.
The program utilizes three different test sites. These sites include: the
Hope Research Center (USDA cold hardiness zone 8a), the Little Rock/Cammack
property (zone 7a), and the Fayetteville Horticulture Research farm (zone 6 b).
