The University of Georgia trial garden has been in existence since 1982, and the method of evaluation and distribution of taxa has evolved over the years. Annual and perennial taxa are evaluated systematically, over the entire season, providing season-long summaries for each one. Annuals are evaluated every 2 weeks, and scores are based on plant performance, including foliar health, flower numbers and the appearance of disease and insect damage. Perennials are evaluated similarly, however flowering time, flowering persistence and height in the landscape are also noted. Summaries for each taxon are presented in tabular and graphic form. Many new crops have been evaluated and introduced to the floriculture industry. New crops are placed in the horticulture gardens and evaluated by garden personnel and by commercial growers and landscapers. Plants have been distributed free of charge to propagators and growers, resulting in rapid market acceptance of successful taxa.

The horticulture research gardens at the Univ. of Georgia were initiated in 1983, and have significantly evolved in visibility and functionality. The gardens were designed to act as a research evaluation site for the industry, but also to be used as a teaching tool for classroom, and to encourage student experience in landscape plant maintenance. Performance evaluation is accomplished by gathering data every 2 weeks, and performance plots are drawn for each taxon at the end of the season. Data on performance of perennial plants are also recorded, and each taxa is summarized after its flowering period. All data is compiled, simplified, and disseminated by booklet, trade magazine papers, and the Internet. In the last 7 years, a major cornerstone of the garden has become the evaluation and introduction of new crops for the ornamental plant industry. At least a dozen new taxa have been introduced. New crop introduction programs will be discussed as a potential means of funding. The ability to initially raise funds for horticultural trials the maintenance of funding over the years will also be discussed.

Rhizomes of Oxalis adenophylla Gillies and bulbs of Ipheion uniflorum Raf. were planted and wet- or dry-stored at 5 °C for 0, 6, 10, 14, or 18 weeks, before being placed in a greenhouse. Regardless of moisture regime, foliage emergence and time to flower decreased for both species with increasing duration of cooling. Wet-stored bulbs/rhizomes within a cooling treatment required less time to foliage and flower emergence when compared with the corresponding dry-storage period. About 10 weeks of 5 °C was optimum for both species.
