A new poinsettia cultivar 'Red Pearl' was bred by the National Institute of Horticultural and Herbal Science (NIHHS) in 2016. This cultivar was derived from the cross in 2013 between 'Freedom Red' with good vigor and dark red colored transitional leaves and 'Little Star' with bright red colored and lobed transitional leaves. From 2014 to 2015, first and second characteristics tests were carried out on growth, flowering, and uniformity, and then 'Red Pearl' was finally selected in 2016 after the third investigation of the growth and flowering characteristics. 'Red Pearl' has bright red bracts and deep lobed transitional leaves with excellent flower form after 7.5 weeks short day commencement. Leaves of 'Red Pearl' are ovate and green color, plant height and petiole length are middle, and greenish stem color has free-branching ability. Stem elongation was excellent even at high temperature in summer, and no physiological disorder due to stress occurred. Plant variety protection right of 'Red Pearl' was registered in January 2018, and its grant number is 6922.
