About String of Pearls (Senecio rowleyanus)
Genus, Species, and Plant Family
The string of pearls has two accepted scientific names: Senecio rowleyanus and Curio rowleyanus.
So, that means the plant’s genus is Curio or Senecio, and its species name is S. rowleyanus or C. rowleyanus. String of Pearls is a member of the plant family Asteraceae, or the daisy family, which comprises over 32,000 species of flowering plants.
Origins and History
The string of pearls is native to dry areas of southwestern Africa. In this native habitat, the plant’s vines creep along the earth, weaving together to form a thick ground cover.
This plant gets its name rowleyanus from Gordon Douglas Rowley, an award-winning British botanist who specialized in succulents and cactus plants. Rowley served as president of the African Succulent Plant Society from 1966 to 1976 and had several plants named after him, including the string of pearls.
Over the years, this species has taken several nicknames other than string of pearls. Here are a few names you may hear others use to refer to the Senecio rowleyanus.
- String of pearls
- String of beads
- String of peas
- String of rosary beads
- Rosary vine
String of Pearls Botanical Characteristics
The string of pearls has trailing, string-like vines. These strings produce green, pea-shaped leaves with a dark band called an epidermal window that allows more light to enter the plant for photosynthesis.
In the spring, string of pearls will produce white blooms with curled pink and orange stamens. These flowers bloom for around one month and give off a fragrance similar to cinnamon or cloves.
Similar Species Grown as Houseplants
This plant can grow with solid green leaves or cream-colored variegated leaves. The string of pearls also has a few relatives with a similar texture and growth habit. Here are a few that you may want to consider adding to your houseplant collection.
- String of watermelons (Curio herreanus)
- String of bananas (Curio radicans)
- String of tears (Curio citriformus)
Uses and Benefits
People cultivate string of pearls most often for ornamental purposes. Senecio rowleyanus is not famous for specific benefits like air purification or Feng shui.
However, the species offers considerable aesthetic value, as it looks beautiful hanging in any space. The plant’s vines spill over its container and contribute a lovely focal point to its indoor environment.
String of Pearls Toxicity and Pet Friendliness
Another great reason to hang your string of pearls plant is that it is toxic if consumed. Humans, cats, dogs, and other animals may experience symptoms like gastrointestinal issues or skin irritation if they ingest any part of the Senecio rowleyanus plant.

However, the good news is that there’s a way to get more longevity out of your string of pearls. You can keep the vines thriving for years and years through propagation.
How to Grow String of Pearls (Senecio rowleyanus)
String of Pearls Growth Expectations
String of pearls vines will typically trail between one to three feet indoors, growing one to two inches per month until it reaches maturity. The plant’s growth speed will vary, depending on environmental factors.
What to Do Before Planting a String of Pearls Plant
Choose a Location
Before planting a string of pearls, you’ll want to find a great location that meets its growth requirements. Consider hanging the plant in a place that receives an even amount of bright, indirect light. Somewhere close to a south-facing window would be ideal.
Avoid spots that get drafts or experience sporadic temperature changes throughout the day.
Find the Right Container
Due to its attractive vining foliage, the string of beads plant grows well and looks great in hanging pots and planters.
The best type of pot will be a porous material like terracotta that minimizes moisture retention and offers more oxygen flow for the plant to enjoy. Additionally, you will want to make sure the container has a drainage hole for eliminating excess moisture.
You may also consider placing the plant in a terracotta pot and draping its vines along a windowsill or side table. However, if you take this approach, keep vines out of reach of pets and ensure they receive even exposure to light.
Gather Your Materials
Now, it’s time to gather the tools you need to plant a string of pearls. Grab its new container and soil, as well as a shovel and gloves if needed. You may also want clippers to help if removing the plant from a plastic container.
What’s the Best Soil Mix to Use for String of Pearls?
Your string of beads plant loves a drier environment, so it will do best in a fast-draining soil like a cactus and succulent mix. It’s best to avoid standard potting mix, as its density and moisture retention won’t be ideal for this plant.
However, if you want to make your own soil for string of pearls at home, you can combine three parts standard potting mix with one part sand to achieve the fast-draining quality this plant prefers. This species does best in soil ranging from a neutral to slightly acidic pH level.
How to Plant String of Pearls
Here are some key tips for planting string of pearls.
1. Purchase a cactus and succulent soil or create your own mix of sand and potting soil.
2. Add a layer of this soil to the planter’s base to ensure the plant doesn’t rest too low inside the container.
3. Allow an inch or so of space around the root ball for the plant to grow.
4. Once you put the plant in its planter, add soil around the sides.
5. Spread vines evenly around the planter to ensure they receive even sunlight.
String of Pearls Light Preferences
Your string of beads plant will do best when placed in a spot with plenty of indirect sunlight. The plant can be more tolerant of lower light conditions than other succulents, especially during winter. This species may enjoy a north or east-facing aspect in the warmer season, as long as it receives enough light during the day.
This plant grows best with around six to eight hours of bright, indirect lighting each day. It may enjoy some direct light during the morning hours, but be sure to protect it from those intense afternoon rays.
Additionally, it’s a good idea to rotate the plant to ensure even light distribution. You may want to rearrange the stems occasionally so that all foliage has access to the sun.
String of Pearls Temperature and Humidity Preferences
Luckily, this plant’s temperature preferences are likely similar to yours. The species does well with temperatures 70 to 80 degrees Fahrenheit in the warmer months.
When the days grow cooler, the string of pearls will prefer temperatures between 50 and 60 degrees Fahrenheit. These lower temperatures will support the plant’s natural dormant phase, so it is rested and ready to bloom once spring rolls around.
As with most succulents, this species enjoys a drier environment. Keep moisture low and avoid placing your string of beads in rooms like the bathroom, where humidity tends to be higher.
How to Care for a String of Pearls Plant at Home
Watering String of Pearl Plants
Now, this plant does prefer a drier environment, but it’s important not to let it sit for long in completely dried-out soil. Its moisture needs will vary depending on the climate where you live, so you may need to experiment to learn your plant’s preferences.
Typically, the string of pearls will need watering to maintain slightly moist soil during its growing season. This will usually be once every week or two. Use your finger to check the soil once a week, and only water if the soil is dry.
Your string of beads plant will likely need more water in the warmer months and less during the winter. Lowering the plant’s water intake during winter will allow it to enter a dormant phase, which will help it produce its beautiful, fragrant blooms come spring. Usually, around once a month is enough water for this plant in the winter.
How, When, and Why to Fertilize String of Pearls
Fertilizing the string of pearls during its growing season, spring through fall, will help it grow robust, healthy foliage. Use a half-strength fertilizer once a month or so during these warmer months. Follow the directions on your fertilizer’s packaging for optimal results.
Pruning String of Pearls
Simply put, the string of pearls does not need much pruning. However, if you notice the vines becoming long and leggy, you may want to prune them slightly for aesthetic purposes. You can also prune the plant’s blooms if you don’t like their look or fragrance, as this will not harm the plant.
Use sharp, clean shears and trim the vines to achieve your preferred length and look. You can do this at any point throughout the year.
Propagating String of Pearls
You can use stems you cut away from the string of beads plant for propagation. Do this whenever you’d like to create a new plant or add volume to the original plant. There are a few easy ways to propagate this species.
- Propagating stems: Snip a stem from the string of pearls and remove about three inches of leaves. Place the bare part of the stem in soil, either in a new planter or in the original pot, and it will take root.
- Propagating leaves: Snip a stem from your string of pearls and leave the pearls intact. In a new planter, place this vine directly into the soil in a spiral shape with the pearls facing up and nodes making direct contact with the soil. Keep the soil moist, and the nodes will take root and form a new plant.
When and How to Repot a String of Pearls Plant
The string of pearls plant doesn’t need frequent repotting. However, a good indicator that it’s time to repot is if the plant has become root-bound.
You can check on the root system by gently pulling the plant out of its container. If it is hard to remove, and its roots appear tangled and crowded, it may be time to repot. Roots poking out from the drainage hole is another indicator of a crowded root system.
If your string of pearls needs more room to grow, find a pot one size bigger than its current container for repotting. This can be an inch or two wider and deeper than the current pot. Here are some basic steps to follow when repotting your string of pearls.
1. Place some soil at the base of your pot to ensure the plant doesn’t sit too low in its new container.
2. Once the new pot is ready, ease your string of pearls out of its container. Start by gathering the strings together to make the transfer as easy as possible. This plant is fragile, so make sure to handle it with care during this process.
3. Place the plant in its new pot and add soil around the sides of its root ball.
4. After repotting, gently arrange the plant’s strings around its container to achieve your preferred aesthetic.
