Hydrangea ( Hydrangea macrophylla ) is popular for landscape gardening and as a flower potted plant life . According to the U.S. Department of Agriculture , sales in the United States increased from 2009 to 2019 , and the sweeping value reached $ 154 million in 2019 . Hydrangea chinensis is an evergreen shrub native to subtropical regions of south and southeastern Asia . This plant life species is commonly seen in woods at low height in Taiwan , flower naturally in early give , and could be used as a parent to breed and select ahead of time - blossom hydrangea progenies .

Researchers from the National Chung Hsing University in Taiwan obtain several interspecific early - blossom hydrangea progenies from crossing Hydrangea chinensis and H. macrophylla cultivars .

newfangled early - flowering hydrangea cultivar / line of work are desirable because tropic and subtropic growers are anxious to reduce the hydrangea susceptibleness to wilt in summertime . In subtropical area , growers can storm some hydrangea to flower for the Chinese New Year market ; however , this off - seasonal production has hardheaded difficulty because of global warming and increase energy costs .

Hydrangea hybrid HB01C-01 , infer from H. macrophylla ‘ Freudenstein ’ × H. chinensis , and CHR06 - 09 , derived from H. chinensis × H. macrophylla ‘ Leuchtfeuer , ’ were choose for their vigorous growth and inflorescence appearance .

Hydrangea chinensis and the intercrossed seedlings blossom starting from February and March , respectively , which is earlier than that of H. macrophylla ‘ Leuchtfeuer ’ and ‘ Freudenstein ’ in May in greenhouse condition . Hydrangea chinensis have white sepal , and the two H. macrophylla cultivar have deep pink ones , whereas most of the intercrossed plants have white or light-colored pinkish sepal , and few hybrids have pink sepals .

Hydrangea hybrid HB01C-01 is suitable for landscape use because of its height , vigorous outgrowth , and bloodless cosmetic sepal that clear up a refinement garden . Hydrangea intercrossed CHR06 - 09 is suitable for potted flowering plant because it has multiple thickset branches , orotund decorative sepals , and smaller leaf .
