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
Also known as
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.

Why is she like this? This girl started out full and now she’s reduced to 4 wimpy leaves that seem to be deteriorating slowly. What can I do?

All watered and happy again. Droopy leaves because it’s thirsty. But a whole lot of new growth as well! Those barrina grow lights work great! #BegoniaEscargot #Begonia #HappyPlants #PlantsMakePeopleHappy #PlantAddict #NewGrowth #PlantTherapy #GrowLights #BeforeAndAfter

Why is my Rex begonia so sad?? Hello! I was looking for some help with my Rex begonia. She has been looking very droopy lately and has progressively browning tips on her leaves and I can’t figure out the issue. I tried switching from tap to distilled water and I also started using a watering bulb because I read she likes consistent moisture instead of being watered every few days but I feel like she just keeps getting worse!! Any help would be appreciated thank you 🙏 #RexBegonia #help

This is my first plant! Any tips on what to expect/do besides waiting to water every 9 days? #Begonia

The leaves on these plants are literally metallic and I am mesmerized by them!! I know it's a begonia, but what kind? I've gotten several answers on my search for an ID. #begonia #happyplants #plantid #greggang #plantaddict #plantsmakepeoplehappy #jesssjungle

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.
