The Phalaenopsis genus, a horticulturally vital group within the Orchidaceae, dominates global floriculture markets through strategic cultivar innovation, scalable propagation, and data-driven cultivation. This review systematically examines the breeding, propagation, cultivation management, and potential applications of Phalaenopsis while providing insights into future research directions. The main contents include the following: Breeding innovations—This review outlines the taxonomy of the Phalaenopsis genus and highlights its intergeneric hybridization potential, which offers vast opportunities for developing novel horticultural varieties. By establishing clear breeding objectives, researchers employ diverse breeding strategies, including conventional crossbreeding and biotechnological approaches (e.g., mutation breeding, ploidy manipulation, genetic transformation, and CRISPR/Cas9 editing). Propagation and cultivation management—Analyses of Phalaenopsis tissue culture protocols covering explant selection, media optimization, and regeneration systems are summarized. Key factors for efficient cultivation are discussed, including temperature, light, water, nutrient management, cultivation medium selection, and integrated pest/disease management. Scientific environmental control ensures robust plant growth, synchronized flowering, and high-quality flower production. Emerging applications—Phalaenopsis exhibits promising applications in functional bioactive compound extraction (e.g., antioxidants and antimicrobial agents). This review summarizes current advancements in Phalaenopsis breeding, cultivation, and potential applications. Based on technological progress and market demands, future research directions are proposed to support the sustainable development of the Phalaenopsis industry.

Paeonia suffruticosa Andr. (tree peony) and Paeonia lactiflora Pall. (herbaceous peony) are traditional Chinese flowers with great ornamental value. To maintain the aesthetic value and show the characteristics of these species, preserved flowers named ‘germplasm display balls’ were developed. Firstly, dried flowers were obtained by vacuum freeze-drying. Secondly, to embed dried flowers and develop germplasm display balls, highly transparent crystal glue (in wrapped display balls type 1 and drop-type display balls type 2) and highly transparent silicone gel (in wrapped display balls, type 3) were used. Finally, the first pass yield (FPY), labor productivity (LP), average cost (AC), and popularity of three kinds of germplasm display balls were compared. The results showed that with the support of a paper cup, the deformation rate of flowers significantly decreased by 91.11%. The FPY of dried flowers was as high as 98.89% at 18 °C. The optimal process for type 1 and type 2 was a glue dosage of 20 g, stirring time of 3 min, and room temperature of 25 °C. Although there was a higher AC in type 3 display ball process, moderate LP and higher FPY and popularity than in other two types, accompanied by high durability, render it the best choice.
