String of Dolphins Plant Distribution

This species was first documented by August Grisebach in 1879 as Senecio peregrinus, using the Latin word for 'dolphin' for its appearance. During the early 1990s, Charles Jeffrey revised the species into the genus of Dendrophorbium, after several morphological tests and studies. Although many believe it's actually a cultivar between the S. rowleyanus and S. articulatus, the Royal Botanical Gardens of Kew states its authenticity as a naturally-occurring species in South America.

How to Grow and Care for String of Dolphins Plant

How to Grow String of Dolphins Plant

  • String of Dolphins Plant Propagation with Seeds
Fill a pot with black peat mixed with a picex in equal parts, and then add water to the substrate. Place the string of dolphins plant seeds on the surface of the substrate and then cover the seeds with a thin layer of pomice or river sand. Finally, place the pot outside, in semi-shade. Water the seeds, but this time with a sprayer. If all goes well, String of Dolphins Plant (Senecio peregrinus) will germinate in 2-3 weeks.
  • String of Dolphins Plant Propagation with Stem Cuttings
Make sure your stem cuttings contain at least 2 to 3 nodes along their length. These nodes are extremely important because they are the points from which propagation will occur. Nodes allow new stems, leaves, and roots to grow out from them. Damaged nodes will reduce the chance of successful propagation. So, be sure you’re using a stem cutting with healthy nodes on it. Having multiple nodes on one stem also improves the chances of successful growth and propagation.
  • Propagating Dolphin Plants Stem Cuttings In Soil
Stick the stem in a well-draining potting mix and give it plenty of water. Don’t worry about overwatering it during propagation. Some gardener friends of mine have suggested using cold water to start the growing process of the roots. When the topsoil has dried out, give the succulents a moderate amount of freshwater. Keep doing this through the next 2 to 3 weeks after propagation. The soil must be fully soaked from the bottom to aid growth.
Propagating Dolphin Plants Stem Cuttings In Water
If you’re growing your stem in water, use clean water that has a pH of around 7.0. Tap water should be fine, but it cannot deviate by a pH of 0.5; any more than that and your stem cuttings or leaf cuttings will have difficulties rooting.
