Origin & Breeding History: 'NCORNSP-030ILPL' originated from a conventional cross between the two proprietary breeding lines 'NC8818-076ORN' as the female parent and 'NC8213-005ORN' as the male parent. The cross was conducted at North Carolina State University, Horticultural Field Laboratory Greenhouses, in Raleigh, North Carolina, USA between October 2017 and April 2018. The new variety 'NCORNSP-030ILPL' was selected from the progeny on September 25, 2019, at the Horticultural Crops Research Station in Clinton, North Carolina, USA based on growth habit, plant vigour, branching characteristics, leaf colour and leaf shape.

Tests & Trials: The comparative trial for 'NCORNSP-030ILPL' was conducted in a polyhouse during the spring of 2023 at Bioflora Inc. in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings transplanted into 15 cm pots on April 17, 2023. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety on June 6, 2023. The mean differences were significant at the 5% probability level based on a paired Student's t-test. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
