String of Dolphins is a highly sought-after, rare succulent with cascading stems of plump leaves that resemble dolphins jumping out of the water. Native to Bolivia and Argentina, this hybrid is an easy grower and only needs a balanced fertilizer once a month during the active growing season. String of Dolphins makes a wonderful hanging basket and can be grown in partial sun or bright, indirect light. Like other senecios, small white flowers that smell like cinnamon appear intermittently.
