To our Trial Program Partners:
The Iowa Arboretum & Gardens Trial Program thanks the plant and seed companies who have generously participated over the years.
Entry Fee
This project, including maintenance of the garden and research conducted, is primarily funded by entry fees collected from plant breeding companies and propagators who have chosen to participate in the trials. The one-time fees are charged for each variety and are due at the time of entry into the program. However, additional financial assistance is welcomed and encouraged from individuals, foundations, garden clubs, nurseries, greenhouse growers, and seed production companies
Herbaceous perennials: $150
