This is the quintessential and most iconic species, famed for its breathtaking nocturnal bloom. The plant produces long, flat, scalloped stems that arch gracefully. Its flowers are exceptionally large, often exceeding 12 inches in diameter, with pristine white outer petals and creamy inner ones. The intoxicating sweet fragrance is a defining characteristic. True to its common name, each magnificent flower unfurls at dusk and wilts by sunrise, a spectacular ephemeral event. It thrives in bright, indirect light and requires a well-draining potting mix. For US growers, it is best grown in containers that can be moved indoors before temperatures drop near freezing.
Often classified as a Disocactus, this hybrid is a staple for growers seeking reliable and prolific blooms. It is valued for its hardiness and adaptability. The stems are more upright and triangular in cross-section when young, flattening out with age. Unlike the Queen of the Night, 'Ackermannii' produces vibrant, day-blooming flowers, most commonly in a brilliant, unfading red. This makes it a fantastic choice for adding a long-lasting splash of color to a patio or sunroom. It is less demanding than some species and can tolerate slightly more direct sun, though protection from intense afternoon rays is still recommended, especially in hotter USDA zones.
This species is primarily grown for its extraordinary and unique foliage rather than its flowers. The stems are deeply lobed in a precise, alternating pattern that strongly resembles a fishbone or the zigzag pattern of a ric rac trim. This dramatic architectural form makes it an exceptional hanging basket plant. While its flowers are lovely—fragrant, nocturnal, and yellow-white—they are secondary to the plant's striking vegetative appeal. It is highly adaptable to indoor conditions and prefers shadier spots than its relatives, making it perfect for bright bathrooms or east-facing windows. Its manageable size is ideal for US growers with limited space.
This hybrid is a champion show plant and a favorite among enthusiasts for its stunning and complex flowers. The blooms are exceptionally large and feature a dramatic color combination: white outer petals with rich, magenta-pink inner petals and a yellow center. The flower structure is intricate and layered, creating a truly magnificent display. 'Helene Oetzel' blooms nocturnally and will often produce a powerful fragrance to attract its pollinators. It requires the standard Epiphyllum care of bright, filtered light and a porous potting medium. For US growers looking to exhibit their plants or simply enjoy a truly spectacular flower, this variety is a top contender.
This bizarre and fascinating cultivar is a must-have for collectors of unusual plants. Its stems mutate into twisted, contorted, and curled forms, creating a dense, tangled mass that looks nothing like a typical cactus. The foliage itself is the main attraction, offering incredible textural interest. It does produce small, pink, nocturnal flowers, but they are often hidden within the chaotic stem growth. 'Monstrosa' is a conversation piece that thrives under the same conditions as other epiphyllums. Its compact and slow-growing nature makes it an excellent and low-maintenance choice for US growers seeking something truly unique for their collection.
