Origin & Breeding History: The variety 'NCORNSP-013GNLC' originated from a conventional cross made at North Carolina State University, Raleigh, North Carolina, USA. Numerous crosses were conducted and the resultant seed harvested between September 2007 and April 2008. The seed was sown in the greenhouse in the spring of 2008 and the first cycle of selection conducted on this seedling population. These selections were transferred into 15 cm pots and maintained in the greenhouse. Two cuttings from each selection were taken in May 2008 and the young plants were planted in the field as two plant unreplicated plots in July 2008 at the Horticultural Crops Research Station in Clinton, North Carolina. The new variety was selected as a single plant on August 15, 2008, based on a combination of exceptional features including plant habit and vigour and foliage colour and shape.

Tests & Trials: The trial of 'NCORNSP-013GNLC' was conducted in a polyhouse during the spring of 2012 in St. Thomas, Ontario. The trial included a total of 15 plants of each variety. All plants were grown from rooted cuttings which were transplanted into 15 cm pots on May 3, 2012. Observations and measurements were taken from 10 plants or parts of plants of each variety on May 31, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
