Plumeria leaves can display various patterns and veining, depending on the cultivar. Some cultivars have leaves with prominent veins and contrasting colors, such as a darker green with lighter veins. Others may have leaves with smooth surfaces and a glossy appearance. Some Plumeria varieties may exhibit variegation, where the leaves have patches or streaks of different colors, adding visual interest to the plant. The diversity of leaf patterns further contributes to the attractiveness of Plumeria as an ornamental plant.
