About Iron Cross 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 been looking for this little guy for while. Absolutely love the texture and color in the leaves.

I’ve recently potted it in the glass, creating a well with soil in the interior... Since the soil/pot size is limited, I’ll plan to water a little sparingly to keep the soil healthy as he settles in. We’ll see how he holds up into spring.

Any tips and trick for this guy are welcome, please ✌🏽
