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! ⚠️

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.
