The present investigation entitled “Evaluation of Lisianthus (Eustoma grandiflorum) cultivars for growth and floral characters under Prayagraj agro-climatic conditions” was carried out from December, 2024 to May, 2025 under naturally ventilated polyhouse, Department of Horticulture, SHUATS, Prayagraj. Fifteen Lisianthus cultivars Arena Red, A Baby Pink, C Purple, A Pink, C Pink Picotee, A White, C Yellow, Croma III Lavender, C White, C Blue Picotee, A Clear Pink, Sunrise White, A Purple, A Gold, and C Green Ain were evaluated in a Randomized Block Design (RBD) with three replications. The results revealed significant variation among the cultivars for all parameters studied. Cultivar Arena Red (V₁) consistently outperformed others in growth and flowering attributes, including plant height (44.5 cm), plant spread (26.7 cm²), number of primary branches (6.9) and number of sprays (6.9). It also recorded the earliest bud initiation (115.3 days) and first flowering (132.5 days). Floral quality was also highest in V₁ with the highest bud length (3.9 cm), bud diameter (2.38 cm), stalk length (11.2 cm) and vase life (11.4 days). Cultivar A White (V₆) followed closely, while C Blue Picotee (V₁₀) showed poor performance in most traits.  Based on the findings, Cultivars Arena Red and A White can be grown for protected cut flower production under Prayagraj conditions.
