String of Arrows Plant Profile 

A vining succulent with exceptional visual appearance, String of Arrows is a member of the Asteraceae family. True to its name, the leaves resemble tiny green arrows with prominent gray venation. Each leaf measures around 2-3 cm in length, and the vines can grow up to 3-4 feet long, making it a perfect choice for decorating small spaces.

The leaves are densely packed along the stem, creating a cascading effect that resembles a flowing river of greenery. If you wish to enjoy the many shades of your Rosary Vines, experiment with the lighting conditions, and you’ll find the succulent leaves tinted with shades of blue and rosy red.

Ideal Pot Size

Pick a container that is one size bigger than the plant’s root ball to avoid pooling of excess water at the bottom, besides providing the roots enough space to breathe. Ideally, a 4-6 inches pot with enough drainage holes is good enough for a young String of Arrows.

You may repot it to a bigger pot when you see the roots peeping out of the drainage holes. Ensure enough holes at the bottom of the container to aid drainage.

Propagating String of Arrows Indoors


Propagating a String of Arrows is relatively easy and can be done in a few simple steps:

  • Locate a robust vine from a healthy String of Arrows plant.
  • Cut a 4-6 inches long section with 3–4 leaves just below the leaf node, using a sterilized pair of scissors.
  • Allow a day or two for the vine’s cut end to callus over. This will prevent it from rotting when buried in the medium.
  • Fill a pot with a well-draining medium and carefully press the vine’s cut end into it, making sure to bury at least one node.
  • Lightly water the newly planted vine, then place it in an area with indirect, bright light. Avoid direct sunlight since it might dry up the soil and burn the foliage.
  • Make sure the soil is continuously moist but not soggy.

It will take 2-3 weeks for the cutting to root and begin to grow. Be patient and avoid disturbing the cutting during this time.

For a breathtaking display of the String of Arrows, provide the plant with ample direct sunlight. Opt for a south-facing window that receives abundant bright afternoon light, and watch the heart-shaped leaves develop a striking exotic red hue. On the other hand, insufficient sunlight can result in the leaves fading to a dull green, so make sure to avoid such situations. However, if you find the leaves getting scorched, move the plant indoors or drape a light-filtering curtain.

During the winter months, when natural light is scarce, supplement the String of Arrows with artificial lightings, such as a grow light, to keep it thriving.


Use a cactus or succulent soil mix to provide good drainage and aeration for String of Arrows. Mix in equal parts of perlite or sand with regular potting soil to create a well-draining potting mix. Avoid heavy or clayey mediums as they retain too much water and cause root rot.

Alternatively, you may also use an orchid mix mixed with a fistful of perlite.

Adjust the frequency of watering based on the season and keep an eye on the top layer of the medium.
