NATURE OF WORK
The ultimate in determining a plant's local production and landscape potential is to grow it. Camellias that had been determined to have cold hardiness potential were planted in clay loam soil in full sun at the Mountain Horticultural Crops Research Station, Fletcher, North Carolina. They were 4 ft apart within the row with 6 ft between rows. There were three single plant replicates of each cultivar in a completely random design. Coldest temperature during the 3-year evaluation period was 5 °F. Plants were only irrigated during extremely dry weather. Weed management was manual plus a directed spray of Roundup or Gramoxone as needed. No fungicides or insecticides were applied at any time during the test. Fertilizer was applied at the rate of 0.5 ounces of nitrogen per plant in early spring from 17N–17P–17K.
A 10-point system was established for evaluating plant performance with 10 = dead plant and 0 = no damage to any part of any plant due to cold or wind. Stem dieback,
