Senecio Peregrinus, or also known as String of Dolphin or Dolphin plant. It’s a rare animal-like variety that develops some beautiful curvy leaves, which perfectly resemble a pod of little jumping Dolphins. String of Dolphins is a cross-pollination of Senecio rowleyanus (String of Pearls) and Senecio articulatus (hot dog cactus). It can grow up to 3 ft long and 15 cm (6 inches) tall, which makes it look great spilling out of a hanging basket or trickling down over bookshelves or even on the edge of a stair rail.
Unlike some rare succulents that can get super tricky with watering, it is pretty easy to water String of Dolphin. The best way to do this is by giving them a good soak of water until it runs out the pot’s drainage hole, and allowing the soil to dry completely in between waterings.
