Dendrobium officinale has important medicinal, edible, and ornamental value, and its flowering performance and floral traits are highly responsive to light and temperature conditions. This study systematically analyzes the effects of light and temperature on floral bud differentiation, flowering phenology, and floral morphological characteristics of D. officinale, and further examines, based on typical cultivation cases, how different light and temperature regimes and their interactions regulate initial flowering, peak flowering, flower number, flowering duration, flower size, flower color, and floral form. The results indicate that normal flowering of D. officinale requires appropriate low-temperature induction during winter, whereas prolonged high temperature or insufficient chilling may lead to delayed flowering, failure to flower, or abnormal floral development. Moderate light helps maintain photosynthetic capacity and assimilate supply, while excessive shading or strong-light stress is unfavorable for floral bud development and floral quality formation. Light and temperature exhibit clear interactive effects, and appropriate chilling combined with moderate irradiance is more conducive to improving flowering uniformity, maintaining stable flower color and floral form, and prolonging flower longevity. Future research should establish stage-specific and precise light–temperature regulation systems for floral induction, bud development, and peak flowering, while integrating flowering regulation with the accumulation of functional components such as polysaccharides, flavonoids, and phenolic compounds to promote the high-value utilization of D. officinale floral resources.
