A new Hibiscus cultivar ‘Tohagol Red’ with unique flower shape and color, uniform growth habit and hardiness was developed through interspecific hybridization between Hibiscus sinosyriacus and H. syriacus. A new cultivar 'Tohagol Red' (Hibiscus × ‘Tohagol Red’) developed after crossing between Hibiscus sinosyriacus ‘Seobong’ ( ♀) with pink flower and Hibiscus syriacus ‘Samchully’ with pink flower to improve flower quality and growth habit in 2002. Hibiscus ‘Tohagol Red’ was preliminarily selected as ‘R 202’ in 2004 for its stable flower quality with rich pink flower and ruffled petals. This cultivar had violet purple, ruffled flowers accented by an intense red eye. Large and showy, the overlapping flower petals formed a complete circle and then named ‘Tohagol Red’ in 2010. The tree showed medium growth habit with slightly upright branch. The selected line was further evaluated for different growth characteristics, leaf shape, leaf size, flowering characteristics, and tested for distinctness, homogeneity, and stability during 2004-2009. In The flowers are medium in size (11 ~ 13 cm) with fan (II-type) petal having width 9.2 cm. Leaves are 7.2 cm long and 5.4 cm wide. After the plant characteristics evaluation for 6 years (2004 ~ 2009), it was registered as a cultivar ‘Tohagol Red’ (3803, No. of plant variety protection rights) in 2011. ‘Tohagol Red’ having violet-purple flower and red eye with ruffled petals is an excellent garden plant.
