A "green echeveria" succulent refers to a variety of the Echeveria plant that features primarily green leaves, typically forming tight rosettes, with fleshy, thick foliage characteristic of most echeverias; they are drought-tolerant, low-maintenance plants that thrive in bright sunlight, need minimal watering, and are often grown in containers due to their compact size and attractive appearance, with some varieties displaying subtle color variations like hints of pink or red on the leaf edges; considered a popular choice for beginner gardeners due to their easy care requirements.
