Begonia Rex vs Queen of the Night Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Begonia Rex
Begonia rex
Begonia rex is a rhizomatous perennial celebrated for its strikingly ornamental leaves. It is primarily grown for its foliage, which exhibits a wide array of colors, patterns, and textures. The leaves can be large, asymmetrical, and often feature combinations of silver, pink, purple, red, green, and brown. While it can produce small pink or white flowers, they are insignificant compared to the foliage. Begonia rex is naturally an understory plant, thriving in humid, shaded environments. It is a popular houseplant due to its unique appearance and relatively compact size, although it can be challenging to maintain indoors.
Queen of the Night
Selenicereus grandiflorus

These stems are typically green to grayish-green, ribbed, and adorned with small spines. It is primarily grown for its spectacular, large, fragrant, white flowers that bloom only at night and wither by dawn. The plant is naturally an outdoor plant, thriving in tropical and subtropical climates. While it can be grown indoors, providing the right conditions for flowering can be challenging.
