The Iron Cross Begonia is typically a robust plant and can reach heights of up to 12-18 inches with an equivalent spread. The leaves can grow up to 8 inches wide, with each leaf unique in its vein pattern, giving the plant its distinct aesthetic appeal.

The Iron Cross Begonia has a rich history. It was first discovered in 1952 near the border of the Guangxi and Guangdong provinces in China. Since then, it has captured the hearts of plant enthusiasts and botanical researchers alike for its unique attributes and captivating beauty.

Growing this plant can be a rewarding experience. However, like all living things, the Iron Cross Begonia requires specific conditions to thrive.
