If you’re thinking of growing gloxinia (Sinningia speciosa), you’re in for a treat! These gorgeous plants, often called Swiss cheese plants because of their unique, perforated leaves, are part of the Gesneriaceae family, which also includes African violets. Gloxinias are well-loved for their stunning bell-shaped flowers that bring a splash of color to any room.
I was introduced to this beauty just a year ago when a friend gifted me a small gloxinia in a pot. At first, I didn’t know much about it, but once it bloomed, I was hooked. Everyone who visited couldn’t help but ask about it. So, I decided to share everything I learned about growing these vibrant plants.
What Soil Is Best For Gloxinia?
Gloxinias are sensitive when it comes to their roots, so the soil needs to be light and well-drained. A mix of peat and sand or a good quality potting mix will work wonders. I personally recommend African Violet Potting Mix—it’s perfect for gloxinias.
How to Water Gloxinia?
Watering your gloxinia correctly is key to keeping it happy. I water mine about once every two to three days, but it’s always a good idea to check the soil. If it feels a little dry on top, it’s time to water. Keep in mind that too much water or not enough can lead to problems, like yellowing leaves. Use a moisture meter to stay on top of it!
During the winter, gloxinias go dormant, so stop watering entirely. When it’s time for the plant to wake up in the spring, resume watering and place it in a warmer, brighter spot. Just make sure not to water directly on the leaves, as this can cause brown spots and invite fungal issues.
How to Propagate Gloxinia?
Gloxinia is easy to propagate, and there are a few methods. I prefer using leaf cuttings, as it’s a gentler option than dividing the tubers. To propagate, simply cut a healthy leaf from your plant and place it in a pot with good potting mix. I usually cut the top half of the leaf to reduce the water demands as the roots form. After about 5-6 weeks, you should see new growth at the base of the leaf.
You can also divide the tubers, but I’ve found that leaf cuttings are less risky for the plant. There’s a great video on YouTube by Azflora explaining tuber division if you want to give it a go.
When Does Gloxinia Bloom?
Under ideal conditions, gloxinias bloom in summer, with flowers lasting through fall. If you’re growing from seed, it takes about five to seven months for the plant to bloom for the first time. It’s worth the wait!
What Fertilizer Is Best For Gloxinia?
Gloxinias don’t need a ton of fertilizer, but they do thrive with a little extra love. I use ALGOplus Liquid Fertilizer, which I also use for my geraniums. It’s perfect for keeping the plant healthy and encouraging blooming. Just be sure not to over-fertilize—moderation is key.
Where to Buy Gloxinia Plants?
You can find gloxinias at most flower shops, especially in late winter and spring. You can also purchase them as bulbs, but this requires more care and patience. Growing them from seeds is another option, though it can take several months for your plant to bloom. But trust me, it’s worth it!
Why Are My Gloxinia Leaves Curling?
If you notice your gloxinia’s leaves curling or rolling downwards, it might be a sign of underwatering or overwatering. It can also happen if the potting mix is poor, the pot is too small, or if the soil is too compact around the roots. Check your watering routine, and make sure your plant has enough space to grow.
Does Gloxinia Need Sun or Shade?
Gloxinias prefer bright, indirect light, but they don’t do well in direct sunlight. During the winter, they don’t need much light, as they go into dormancy. In the summer, you can place them near a window but make sure they’re not exposed to too many hours of direct sun. Gloxinias can also be taken outdoors in the summer, as long as they’re in a shaded area.
Is Gloxinia an Indoor or Outdoor Plant?
While gloxinia is typically an indoor plant, it can be moved outdoors in the spring after the frost has passed. Just be sure to keep it in a spot where it gets indirect light, and avoid putting it in full sun.
Why Is My Gloxinia Dying?
If your gloxinia seems to be dying, don’t panic! Common causes include overwatering, poor drainage, lack of light, pests, or nutrient deficiencies. If it’s the off-season, don’t worry if it looks like it’s drying out. Gloxinia enters a dormant phase during the winter, and it will come back to life in the spring.
Is Gloxinia Toxic to Pets?
Good news! Gloxinia is considered non-toxic to humans, according to the California Poison Control System. As for pets, it’s generally safe for cats and dogs, but it’s always a good idea to monitor their behavior. Even non-toxic plants can cause mild stomach upset if ingested in large quantities.
With all these tips, you’re ready to take care of your gloxinia! This gorgeous plant is not only easy to grow but also incredibly rewarding. Just give it the right conditions, and you’ll be enjoying its stunning blooms in no time.Tools
