“…Incompatibilities between parents in an interspecific or intergeneric cross may lead to poor seed set. In crosses between Chimonanthus praecox and Chimonanthus nitens, even though successful fertilization occurred in 30.4% of pollinations, 100% of embryos aborted by 25 d after pollination due to the low number of viable embryos that developed and the complete failure of the endosperm to develop (Wang et al, 2014).…”

Four species of Dissotis and three species of Tibouchina, two genera of the Melastomataceae family, were crossed in an attempt to create interspecific and intergeneric hybrids. Intergeneric crosses set seed at a rate of 18.1% and interspecific crosses had a 32.3% rate of seed set. Germination was extremely poor, with only four crosses having germinated seed. Crosses produced 31 seedlings. Three of the seedlings were from intergeneric crosses between Dissotis canescens and Tibouchina lepidota. Interspecific crosses produced 25 seedlings from crosses between Dissotis princeps and Dissotis rotundifolia and three seedlings from crosses between D. canescens and D. princeps. The prognosis for conventional breeding for species in Dissotis and Tibouchina is poor due to low seed set, poor germination, and slow growth of progeny.

“…Historically, taxonomic studies of the Chimonanthus genus have predominantly depended on morphological characters ( Dai et al, 2012 ). However, relying solely on morphology for describing and delineating this genus presents challenges, as these characters can be influenced by environmental factors and may vary across different physiological phases of plants ( Wang et al, 2014 ). Past morphological studies have suggested varying numbers of Chimonanthus species, ranging from three to six, and even up to nine based on different morphological evidence ( Fan et al, 2010 ; Dai et al, 2012 ).…”

“…In terms of cultivation, wintersweet thrives in full sun with moist soil, commencing its flowering in late December and potentially extending into March ( Wang et al, 2014 ). Hardy to the low end of zone 7 (0 degrees), it may experience later flowering and risk frost damage near freezing temperatures ( Shang et al, 2020 ).…”

“…Wintersweet responds well to aggressive spring renovation, generating numerous new stems, but it may exhibit sporadic flowering for several years due to its tendency to bloom on the previous year’s wood ( McCann, 2022 ). Interestingly, a plant grown from seed may take up to 14 years to bloom for the first time, and there’s a peculiar behavior where it may not flower if growing vigorously ( Wang et al, 2014 ). This nuanced nature adds to the allure and intrigue of cultivating Chimonanthus praecox , making it a plant with both ornamental and historical significance ( Wang et al, 2014 ).…”

Floral color and scent profiles vary across species, geographical locations, and developmental stages. The exclusive floral color and fragrance of Chimonanthus praecox is contributed by a range of endogenous chemicals that distinguish it from other flowers and present amazing ornamental value. This comprehensive review explores the intricate interplay of environmental factors, chemicals and genes shaping the flower color and fragrance of Chimonanthus praecox. Genetic and physiological factors control morpho-anatomical attributes as well as pigment synthesis, while environmental factors such as temperature, light intensity, and soil composition influence flower characteristics. Specific genes control pigment synthesis, and environmental factors such as temperature, light intensity, and soil composition influence flower characteristics. Physiological processes including plant hormone contribute to flower color and fragrance. Hormones, notably ethylene, exert a profound influence on varioustraits. Pigment investigations have spotlighted specific flavonoids, including kaempferol 3-O-rutinoside, quercetin, and rutin. Red tepals exhibit unique composition with cyanidin-3-O-rutinoside and cyanidin-3-O-glucoside being distinctive components. Elucidating the molecular basis of tepal color variation, particularly in red and yellow varieties, involves the identification of crucial regulatory genes. In conclusion, this review unravels the mysteries of Chimonanthus praecox, providing a holistic understanding of its flower color and fragrance for landscape applications. This comprehensive review uniquely explores the genetic intricacies, chemical and environmental influences that govern the mesmerizing flower color and fragrance of Chimonanthus praecox, providing valuable insights for its landscape applications. This review article is designed for a diverse audience, including plant geneticists, horticulturists, environmental scientists, urban planners, and students, offering understandings into the genetic intricacies, ecological significance, and practical applications of Chimonanthus praecox across various disciplines. Its appeal extends to professionals and enthusiasts interested in plant biology, conservation, and industries dependent on unique floral characteristics.
