Gloxinia Care

Gloxinia, also known as Sinningia speciosa, is a beautiful flowering plant that’s loved for its velvety leaves and vibrant blooms. You can grow this plant in your home with the right care. This article will guide you through all you need to know to keep your gloxinia healthy and flourishing.

Scientific Classification

When you look at a Gloxinia, you’re seeing a plant that scientists have sorted into different groups. Each group tells you something about the plant, like what other plants are its cousins or where it originally comes from. Here’s how Gloxinia fits into the plant world:

  • Kingdom: Plantae
  • Subkingdom: Tracheobionta
  • Superdivision: Spermatophyta
  • Division: Magnoliophyta
  • Class: Magnoliopsida
  • Subclass: Asteridae
  • Order: Lamiales
  • Family: Gesneriaceae
  • Genus: Sinningia
  • Species: Sinningia speciosa


Gloxinia plants love bright light, but not direct sunlight. Think of how the sun filters through thin curtains; that’s the kind of light they need. If the sun is too strong, it can burn the leaves, causing them to turn brown and crispy. But if there’s not enough light, the plant won’t bloom well. The best place for your Gloxinia could be near a window that gets plenty of light, but with a little shade. This spot will encourage the plant to grow large, vibrant flowers. Remember to turn the pot occasionally. This ensures that all sides of the plant get enough light and grow evenly.


Gloxinia plants need just the right amount of water to thrive. You should keep the soil moist, but not too wet. Overwatering can lead to problems, like root rot. On the other hand, letting the soil dry out too much can stress the plant. Water gloxinias when the top inch of soil feels dry. Use room temperature water, because cold water can shock the roots. Always pour water directly onto the soil, avoiding the leaves and flowers. This helps prevent fungal diseases that can happen if the leaves stay wet for too long. In short, consistent and careful watering is key to a happy gloxinia.


Soil is like a cozy bed for your Gloxinia plant’s roots. You need to get it just right for your plant to be happy. Imagine your favorite spot to relax; that’s what good soil is for Gloxinia. It should be fluffy and light, so the roots can breathe and drink water easily. This type of soil is often called “well-draining.” It means that water won’t sit around too long and make the roots soggy. If the roots are too wet, they can rot, which is bad for the plant. To get soil like this, you can mix things like peat moss, perlite, and vermiculite together. These materials help the soil stay airy and keep the right amount of moisture. Good soil provides a balance – not too wet, not too dry, just perfect for your Gloxinia to grow well.


Gloxinia plants like it warm, but not too hot. They thrive in a temperature range of 60-75 degrees Fahrenheit. If it gets colder than 60 degrees, they can get damaged. In the heat of summer, if it’s over 75 degrees, they could wilt or not grow well. Keep your gloxinia in a place where the temperature stays pretty steady. Avoid putting it near drafts, like by an open window in winter or an air conditioner in summer. If the leaves turn yellow or fall off, it might be too cold, and if the plant stops flowering, it could be too hot. Keeping your gloxinia happy with the right temperature will help it grow beautiful flowers.


Humidity is the amount of water vapor in the air. Gloxinia plants like moist air around them, but not too wet. They don’t do well in dry air like what you might find in your home during winter. To keep your Gloxinia happy, aim for humidity levels similar to what you’d feel on a spring morning, which is around 50-60%. If the air is too dry, you could use a room humidifier or place a tray of water near your plant. The water will evaporate, adding moisture to the air around it. Do not let the bottom of the pot sit in the water, as that can cause root rot. Keeping Gloxinia at the right humidity level helps it grow healthy leaves and flowers.


Fertilizer is food for your Gloxinia plant. It needs nutrients to grow healthy and bloom. During the growing season, feed your Gloxinia every two weeks. Use a balanced liquid fertilizer, which has equal parts of nitrogen, phosphorus, and potassium. Mix it with water as the package directs. Do not fertilize when the plant is dormant. This is usually in the winter when it stops growing. Over-fertilizing can hurt your Gloxinia, so stick to the schedule. With proper feeding, you’ll see lusher leaves and more flowers.

Size & Growth Rate

Gloxinia plants have a medium pace of growth. They can reach up to 12 inches in height and spread out to roughly 24 inches. The leaves themselves can grow quite large, making the plant look full and lush. During their growing season, which is spring and summer, they will grow the most. It’s vital to give them the right care so they can reach their full size. However, in the fall and winter, they go dormant. This means they stop growing and may even look like they’re dying. But don’t worry—they’re just resting and will be ready to grow again once spring arrives. With proper care, your Gloxinia should thrive and reach its full size within a few months. Remember, they may not grow very fast, but with patience, they will become beautiful and robust plants.

Common Issues

When caring for Gloxinia plants, you might face a few problems. These issues can make your plant unhappy. One common issue is overwatering, which leads to root rot. If you see yellow leaves, it might mean too much water. Pests like aphids and mites can also bother your Gloxinia. These bugs suck on the plant, weakening it. Fungal infections could show up as spots on the leaves or a kind of white growth. Too much direct sunlight can scorch the leaves, leaving them with brown marks. If your Gloxinia doesn’t bloom, it may not be getting enough light or the right nutrients. Watch your plant for signs of trouble and act fast to help it stay healthy.


When we talk about toxicity, we’re discussing how poisonous a plant is. For the Gloxinia, it’s generally safe for people and pets, which is good news. This means you, your dog, or your cat can be around this plant without worrying about it making anyone sick if touched. However, it’s always best to be cautious and prevent pets from chewing on any plants because individual reactions can vary. If a pet has a tendency to nibble on greenery, it’s wise to monitor them or place the Gloxinia somewhere out of their reach. Always remember, safety comes first, so keep plants away from small children and curious animals just to be on the safe side.

Pro Tips

When caring for your Gloxinia, here are some tips to help it thrive:

  • Place your plant in a bright room, but away from direct sunlight.
  • Water it when the top inch of soil feels dry.
  • Use well-draining soil so its roots don’t sit in water.
  • Keep the room warm, ideally between 60-75°F.
  • Maintain a high humidity level by misting the plant or using a humidifier.
  • Feed it with a balanced fertilizer every few weeks during the growing season.
  • Be patient, as Gloxinias can take a while to bloom.
  • Watch out for droopy leaves, which can signal too much water or not enough humidity.
  • Rotate the pot regularly for even growth and flowering.
  • After blooming, let its leaves die back naturally before the next growing season.
