This research explores the comprehensive strategies from resource screening to garden landscape design, focusing on the cultivation, ornamental properties, disease management, and environmental adaptability of Clematis species. Clematis species are renowned for their diverse flower shapes and colors, making them ideal for vertical landscaping and garden aesthetics. Research conducted in the Stavropol Botanical Garden identified 29 varieties with high ornamental value, emphasizing the importance of flower shape, size, and color in selection for vertical gardening. Additionally, Clematis tientaiensis, an endangered species, demonstrates specific light requirements for optimal growth, highlighting the need for appropriate light management in garden design. Disease management is crucial for maintaining the health and aesthetic value of Clematis. Common diseases such as wilt, rust, and powdery mildew, along with pests like nematodes and aphids, pose significant threats. Effective agrotechnical measures and pest control strategies are essential for sustainable cultivation. Environmental adaptability studies reveal that Clematis species exhibit varied responses to abiotic stresses such as heat and light. For instance, Clematis crassifolia and Clematis cadmia show different physiological and molecular responses to heat stress, which can inform breeding and cultivation practices. Similarly, the adaptability of Clematis tientaiensis to different irradiance levels underscores the importance of environmental considerations in landscape design. In conclusion, the integration of Clematis species into garden landscapes requires a multifaceted approach, encompassing careful selection of varieties, disease management, and environmental adaptability. This research provides a foundation for future research and practical applications in ornamental gardening and landscape architecture. Keywords Clematis; Ornamental plants; Vertical landscaping; Disease management; Environmental adaptability; Garden design; Perennial vines Introduction Clematis, a genus within the Ranunculaceae family, is renowned for its diverse and widespread species, which are highly valued in horticulture for their climbing habit and vibrant flowers (Figure 1). The genus includes over 300 species, many of which are cultivated as ornamental plants in gardens worldwide (Špetík et al., 2022). Clematis species are not only appreciated for their aesthetic appeal but also for their ecological roles and medicinal properties. For instance, several species have been traditionally used in ethnopharmacology to treat various ailments, including nervous disorders, syphilis, and gout (Chawla et al., 2012). The genus is also of significant taxonomic and phylogenetic interest due to its complex infrageneric relationships and diverse morphological characteristics (Lehtonen et al., 2016; Ghimire et al., 2020). Integrating resource screening with landscape design is crucial for optimizing the use of Clematis species in horticulture. Resource screening involves identifying and selecting species with desirable traits such as disease resistance, growth habit, and flower characteristics. This process is essential for developing sustainable and resilient garden landscapes. For example, understanding the phylogenetic relationships and taxonomic classifications within Clematis can aid in selecting species that are best suited for specific environmental conditions and aesthetic requirements (Lehtonen et al., 2016; Phukhamsakda et al., 2020).
