My alley is resplendent with ten areca palms arranged in two straight rows. The areca palm trunks are round, reaching up high, silvery in color, each ring like a jewelry ring. The fresh green areca palm leaves bend like soft hands, dancing beautifully in the gentle breeze. On summer nights, the fragrance of areca flowers spreads, filling the space. The areca palms, each as big as a chicken egg, have shiny green skin. Four seasons have passed, the areca palms are still pristine, standing there like close friends in my family's familiar garden.
