Costa Farms 2016 Field Trial Results

Costa Farms trials some 200 varieties every spring in its 2-acre trial garden in Miami, FL. Most plants were grown in 6-inch pots prior to transplant and started from unrooted cuttings or seed. They were transplanted into the trial garden between December 13 and January 8. Miami’s tropical climate, with its heat and humidity, always tests the durability of the entries. Costa Farms also trials hundreds of perennials each year at its 1-acre garden in Trenton, SC. (Zone 8A). Trial managers evaluate them for summer and winter performance over two seasons.
