Begonia
WAX, TUBEROUS, CANE, RHIZOMATOUS, REX
There are so many different varieties of begonia. Some have showstopping leaves with crazy colors and patterns, while others have modest leaves with large colorful blooms. Some are better for indoor while others are able to live outdoor, even in New Mexico.
Begonias can be separated into 5 classifications, based on growth pattern and physical characteristics—which affect humidity and watering requirements.
Wax begonias grow low to the ground, have bright flowers and are great for garden bedding. As long as they’re in a shaded area and watered every 1-2 days, they can even survive in your NM garden bed well into the Fall.
Tuberous begonias are good container plants for the patio. They produce large rosette-shaped flowers with vibrant colors.
Cane begonias, like Angel Wing begonias (pictured) have dramatic leaves and grow upright with a thick stem. They make great houseplants.
Rhizomatous begonias, like the Iron Cross, grow horizontally from rhizomes, creeping along the soil. They also have bright, showy leaves and go well in hanging baskets. In NM, these do well as houseplants.
Rex begonias are technically rhizomatous but are sometimes separated into their own 5th classification. This is because their leaves are more thin/delicate, they’re more prone to rot, and they are less forgiving to lower humidity than other rhizomatous varieties.

Rex need more drainage but still water-retentive and airy. -
Begonias need humidity, whether that’s from a humidifier or frequent misting—some types are very prone to fungus, so leaves should not stay wet for too long
They like a moist room, not moist roots. Air circulation is important.
They would do really well in a bathroom with a small frosted window.Large plants may need support from stakes and ties. Begonias can get BIG.
