About Rex Begonia
There are over 2,000 species of Begonia, and horticulturalists have created even more varities by cultivating all sorts of shapes and colors! They're native to tropical regions around the world, but are now found in homes in cold climates as well. Their taxonomy is far more complex than other plants, with species belonging to different cultivar groups. They contain oxalic acid, so be sure to keep them out of reach in homes with pets or children! ⚠️
Taxonomy
Begonia rex-cultorum
Begonia
Begoniaceae
Cucurbitales

rex begonia fedor

Finding light for Rex Begonia in your home
a window
Rex Begonia may have difficulty thriving, and will drop leaves 🍃, without ample sunlight.
Place it less than 3 feet from a south-facing window to maximize the potential for growth.
Select your region to see how the current weather in your area affects the placement of Rex Begonia in your home 🏡.
How to fertilize Rex Begonia
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Rex Begonia after it doubles in size or once a year—whichever comes first.

Is the begonia not getting enough light,looks stems are a abit leggy,or is this normal? It has flowers so it should be happy. But I'm just wondering

My Rex begonia is grown over and slouching. Should I prop it up on a stick or leave it the way it is? #Begonia

Looks sad and droopy. Wasn’t this way two days ago. Should I get a glass covering for it? Prop it up? Does it have just seasonal depression? Thanks in advance for advice #HappyPlants #Begonia #PlantsMakePeopleHappy

Check out this Begonia Escargot I’m planning to put up for sell within the next couple of days! Very pretty! Look at those beautiful spirals! The leaves are getting to be bigger than my hand now. Which means it’s taking up a lot of space in my ikea greenhouse. The last picture shows this begonia (big leaf on top) next to my smaller baby begonia that I’m also going to sell(2 smaller leaves on bottom) #HappyPlants #PlantsMakePeopleHappy #PlantAddict #PlantTherapy #GrowLights #BeforeAndAfter #PlantLove #TropicalPlants #ThanksForPhotosynthesis #QuickGrowingPlants #Begonia #BegoniaEscargot #BegoniaRex

Got it finally Few months ago I was walking in a greenhouse, for the first time I saw that beautiful silver plant. I felt in love with begonias instantly, I knew I needed it in my collection. Yesterday I got my own; I'm so happy and mesmerized by the beauty of #Begonia , such amazing colors and interesting patterns. Im excited to make it thrive

Anyone know what's wrong with this Rex Begonia? I just recently started expanding from succulents, so I'm not super sure why so many of the leaves are drooping. It was a bit rough looking when I got it about a week ago, but there wasn't much change since then, so I went ahead and repotted it while I was repotting everything else. (I used 2 parts Miracle Gro Oraganic Potting Mix and 1 part perlite) The other one I have seems to be doing better, still some wilting leaves, but it had more to begin with so it doesn't look nearly as pathetic and I'd like to figure out the issue so I don't lose both. To my knowledge, begonias are sensitive to humidity and light intensity, so I think that one or both of those must be the main culprit, but I'm not sure how to tell if it's one or the other because the symptoms seem similar #growlights #sickplants #begonia #plantaddict

What am I doing wrong??? #Begonia My begonia just won’t stay alive. She started wilting a week ago, so I gave her a break from water, she started wilting even more so I gave her extra. I thought it might’ve been the sun so I took her away from directly in the window. Now she looks like this

I’ve had my rex for 2 years now. Nothing but positive things from this plant! It droops when it needs water and is able to survive with direct and completely indirect light! Plus they’re super cute ☺️

This plant is so easy for me to take care of! I keep him on a high shelf with indirect light and within 2 months he has already almost doubled in size! So many new leaves! No pests i’ve noticed so far.

The coloring of this plant’s leaves is spectacular and really unique. I have the Red Splash variety of Rex Begonia and I love the jagged edges with their silver/gray stripes. This one has clung and flourished despite being in a forgotten planter outside until it was quite cold. It’s really a hardy, beautiful little plant!

This is my 3rd begonia added to my collection, and while I previously thought they were dramatic and easy to kill, I’m finding my begonias are proving me wrong, this one too. Betty likes the bathroom windowsill, bright indirect light, water about once a week. I love the variegated leaves.

I bought this plant from Lidl when it was wilting and basically dead. The minute I took it home and put it in water is perked up! It’s the easiest plant to take care of because the leaves droop when it needs water, and once you water it, an hour later it perks back up!

NOT TOLERANT TO HEAT. I don't recommend putting it in a hot room with no AC especially during the summer. Also give it some time if it looks dead because it can make a comeback.
