These plants were noted for their dark leaves with prominent silvery grey bands. They are actually a type of rhizomatous begonia, which means "a thickened stem from which leaves arises". The leaves can be multi-coloured with shades of green, red, brown, and silver. Rex begonias produce delicate flowers but are usually grown for their spectacularly colored and intriguingly textured leaves. Some leaves are toothed and variegated, while others are margined. Most leaves are crinkled. Other common names for these plants are fancy-leaf, painted-leaf or king begonias.
