Scientific Classification

Every living thing has a scientific name that tells us exactly what it is. The String of Pearls Plant is no different. Its special name fits into a system that organizes all plants and animals. This helps scientists from all over the world talk about the same thing without getting confused. Here’s how the String of Pearls Plant fits into this system:

  • Kingdom: Plantae
  • Order: Caryophyllales
  • Family: Asteraceae
  • Genus: Senecio
  • Species: S. rowleyanus


Your String of Pearls plant loves bright, indirect sunlight. It’s a bit like you preferring to wear sunglasses on a sunny day. Too much direct sunlight can harm it, much as a sunburn would hurt you. Find a spot in your home that gets plenty of light, but not where the sun will beat down on the plant for hours. Think of a place near a window with a sheer curtain. This curtain gives the plant the protection it needs. If you see the leaves turning a yellow shade, that means it’s getting too much light. On the contrary, if the plant starts to stretch out, it’s reaching for more light. Find that perfect spot with the right amount of light, and your plant will thrive.


The String of Pearls plant needs a balance when it comes to watering. You don’t want to flood the plant. Yet, it can’t get too dry. Water it every two weeks or so, but always check the soil first. If the top inch is dry, then it’s time to water. Pour water evenly until it trickles from the drainage holes. But be careful. If the soil stays wet for too long, the roots can rot. In winter, cut back on watering. The plant takes a rest and uses less water. Remember, it’s better to under-water than over-water. This plant can bounce back from dryness but not from too much water.


The soil you use for your String of Pearls plant is really important. It must drain water well because too much water can make the plant’s roots rot. Think of the soil like a sponge that needs to dry out between waterings. You need a mix that’s light and airy rather than heavy and dense. Usually, people use a special type called “succulent and cactus mix.” You can find this at most garden stores. It’s made to hold just enough moisture for plants like the String of Pearls without staying wet for too long. Therefore, choosing the right soil keeps your plant healthy and happy.


The String of Pearls plant likes to be warm. It thrives when the temperature is between 70°F and 80°F during the day. At night, it prefers a slight drop, but keep it above 60°F. If it gets too cold, this plant can have a hard time. It cannot survive frost or freezing temperatures. Therefore, in places where winters are cold, it’s best to keep your String of Pearls plant indoors. If you live in a warm climate all year round, your plant will do well outdoors. Remember to move it inside if a cold night is forecasted. Temperature matters a lot for this plant, so keep an eye on the weather.


Humidity is the amount of water vapor in the air. For your String of Pearls plant, it’s the level of moisture it needs from the environment to stay healthy. This plant doesn’t require high humidity; in fact, it prefers drier conditions. It’s much like a cactus in this way. If the air in your house is very dry, you might occasionally mist the plant. However, you don’t want to do this too often. Too much humidity can cause problems, like making the pearls squishy or leading to rot. It’s best to keep your plant in a room with normal air moisture. If you live in a humid climate, make sure your plant has good air circulation. This will help keep the humidity around your plant just right.


Fertilizer feeds your String of Pearls plant. Just like you need vitamins to grow, your plant needs fertilizer to get nutrients. But don’t overdo it. Too much, and you can harm your delicate plant. Instead, use a liquid fertilizer that is half-strength. Do this every month during the spring and summer, when your plant is growing the most. In fall and winter, your String of Pearls rests and does not need fertilizer. Stick to this schedule, and your plant will thrive. Remember, the right amount at the right time makes all the difference.

Size & Growth Rate

The String of Pearls plant grows at a moderate pace and doesn’t get very big. This means you won’t have to worry about it taking over your space. Typically, the plant trails down from the pot and can reach lengths of up to two to three feet when cared for properly. The round, bead-like leaves give the plant its name and they grow on thin, trailing stems. These stems can get longer over time, but the overall size of the plant remains manageable. When you give your String of Pearls the right amount of light and water, it will grow steadily. However, if conditions aren’t ideal, the growth rate might slow down or the plant could stop growing altogether. Therefore, to keep your plant healthy and growing, make sure to provide the care it needs.

Common Issues

When you care for a String of Pearls plant, you might face some problems. These plants can get too much or too little water. If the leaves shrivel, they need more water. If they’re mushy, you’ve given them too much. Bugs like gnats and mealybugs may try to live on your plant. They can harm it by eating the leaves or sucking the sap. If your plant does not get enough light, it might not grow well. It may stretch towards the light, and the pearls will be spaced out. Too much sun can burn the leaves, leaving brown spots. The soil can also cause trouble if it holds too much water. This might lead to root rot, which could kill the plant. Make sure you check your plant often so you can spot these issues early on.


Toxicity is about how poisonous a plant is. The String of Pearls plant, while beautiful, is not safe to eat. It has toxins that can harm pets, like cats and dogs, and people if they swallow it. After touching the plant, it’s a good idea to wash your hands. This especially matters if you then eat or touch your face. It’s best to keep the plant away from children and pets. If someone does eat part of this plant, they might feel sick. Symptoms like drooling, vomiting, and diarrhea can happen. It’s not likely to be deadly, but it’s still serious. If you think your pet or child has eaten any, you should get help from a doctor or vet right away. Always handle plants with care and know which ones are safe.

Pro Tips

When you care for your String of Pearls plant, you’ll want to keep some tips in mind:

  • Place it in bright, indirect light: Too much direct sun can burn the leaves.
  • Water sparingly: Wait for the soil to dry out before watering again.
  • Use well-draining soil: This prevents water from pooling around the roots.

  • Maintain humidity: Aim for moderate humidity and consider using a pebble tray with water.
  • Don’t fertilize too much: Feed it lightly during the growing season.
  • Prune regularly: Trimming back can encourage fuller growth.
  • Watch for pests: Keep an eye out for common pests like mealybugs and treat them promptly.
