A succulent collection consists of various types of succulent plants, which are known for their thick, fleshy leaves and stems that store water. These plants are popular among gardeners and plant enthusiasts due to their unique shapes, colors, and low maintenance requirements. Common examples include aloe vera, jade plant, and echeveria. To create a successful succulent collection, it's essential to provide proper care, including well-draining soil and adequate sunlight. Succulents thrive in dry conditions, so overwatering should be avoided. Collectors often enjoy arranging their plants in decorative pots or terrariums, showcasing their beauty and diversity.
