A new cultivar 'Daemang' ($Hibiscus$ hybrid 'Daemang') originated from the interspecific cross between $Hibiscus$ $sinosyriacus$ 'Seobong' and $Hibiscus$ $syriacus$ 'Namwon' to improve the flower quality in 2001. 'Daemang' was preliminarily selected as 'R-143' in 2003 for its stable flower quality with long red eye spot and named in 2006. The tree habit shows vigorous growth and is upright, so it can be used as a specimen tree or street tree. Characteristic tests such as leaf shape, leaf size, flower characteristics, flowering, and capsule size were conducted from 2004 to 2006. The characteristics succeed after grafting. 'Daemang' had pink color flower with red eye spot. The width of flower is 15.2 cm. Petal length and width are 8.0 cm and 6.4 cm, respectively. Leaves are 9.49 cm long and 8.72 cm wide. After the plant characteristics evaluation for 3 years (2004~2006), it was registered as a variety 'Daemang' in 2008.

A new Hibiscus cultivar 'Daewangchun', having vigorous growth, uniform plant habit, upright, compact branches, and a long red eye was developed through interspecific crosses between H. syriacus 'Samchully' (♀) and H. sinosyriacus 'Seobong' (♂). The Hibiscus breeding program was initiated in 2005 and Hibiscus ${\times}$ 'Daewangchun' was preliminarily selected as '05-R-204' in 2 008 due to its vigorous growth and stable flower quality w ith rich pink flowers. The s elected line was further evaluated for different growth characteristics, leaf shape, leaf size, and flowering characteristics, as well as tested for distinctness, homogeneity, and stability during 2010-2012. The new cultivar 'Daewangchun' had violet pink flowers (RHS N80C) with a long red eye spot, medium size and fan petals. The size of flower was 12.0 cm and size of the red eye was 3.0 cm. Leaves were 8.7 cm long and 4.7 cm wide. After plant characteristic evaluation for 3 years (2010-2012), 05-R-204 was registered as cultivar 'Daewangchun' (4731, No. of plant variety protection rights) in 2013. This newly developed cultivar 'Daewangchun' has tall vigorous growth and unique flowers with a long red eye and can be used as specimen plants in landscaping.

This study was carried out to characterize 127 recently developed cultivars of Rose of Sharon (Hibiscus spp.) in Korea and foreign Countries for landscape uses. The examined factors were growth characteristics such as tree height of a 1-year grafted plant(cm), plant type, growth habit, leaf characteristics such as shape and size, flower characteristics such as color, shape, size, and red eye during 2014 and 2015 for landscape uses. The results are obtained as follows; Hibiscus hybrid 'Daewangchun', 'Daeil', 'Lohengrin', 'Yeonam', 'Joomong', 'Jina', and H. syriacus 'Honggarosu' had vigorous shoot growth and tall tree size of 100cm. New Hibiscus cultivars, Hibiscus hybrid 'Daewangchun' and 'Daeil', having vigorous growth, uniform plant habit, upright, and compact branches were developed through interspecific crosses between H. syriacus 'Samchully' (♀) and H. sinosyriacus 'Seobong' (♂). This newly developed cultivar 'Daewangchun', 'Daeil', 'Lohengrin', 'Yeonam', 'Joomong', 'Jina', and H. syriacus 'Honggarosu' having tall vigorous growth d unique flower with long red eye can be used as street tree or specimen plant in landscape. Otherwise, H. syriacus 'Tamla', 'Melrose', 'Bidan', 'Hi Lea', 'Byeollee', 'Byunghwa', 'Mibak', 'Hanyang', 'Chungam', 'Lil Kim Violet', 'Jongmoo', 'Eunhasu', Hibiscus hybrid 'Saehanseo', and Hibiscus hybrid 'Yousoon' were selected as small tree of 30~39cm. They had dwarf form in tree seemed to be suitable for pot or flower bed planting on both indoor and outdoor conditions. H. syriacus 'Antong', 'Chungjo', and 'Lil Kim' were less than 30 cm of tree size. H. syriacus 'Antong', 'Chungjo', and 'Lil Kim', characterized by its compact, upright and outwardly spreading plant habit; freely branching habit; dark green-colored leaves; good garden performance. Therefore, the new cultivars with tall and small tree size were a promising cultivar as a ground covers or pot planting as woody landscape plant.
