Night Blooming Cereus vs Purple Leaf Plum Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Night Blooming Cereus
Selenicereus grandiflorus
Selenicereus grandiflorus, commonly known as Night Blooming Cereus, is an epiphytic or lithophytic cactus characterized by its long, sprawling, and often climbing stems. These stems are typically green to grayish-green, ribbed, and may have aerial roots. It is primarily grown for its spectacular, large, white, and highly fragrant flowers that bloom only at night and wither by dawn. This plant is naturally an outdoor plant, thriving in tropical and subtropical climates. People cultivate it for its unique nocturnal blooms and sweet vanilla-like fragrance.
Purple Leaf Plum
Prunus cerasifera
The Purple Leaf Plum is a deciduous tree known for its striking purple foliage that persists throughout the growing season. It typically reaches a height of 15-25 feet with a similar spread. In spring, it produces delicate pink or white flowers before the leaves emerge. While primarily an outdoor ornamental tree valued for its vibrant color and spring blossoms, it is not suited for indoor cultivation due to its size and high light requirements.
