One way to differentiate between a true Christmas cactus and a false Christmas cactus is by examining the stems. The true Christmas cactus will have stems that arch downwards in a graceful manner, giving it a more closed and compact habit. On the other hand, the false Christmas cactus may have stems that grow in various directions, without the distinct arching downward pattern.
When observing the margins of the stems, the true Christmas cactus will have rounded edges with small visible points or nubs. These points add to the overall texture and appearance of the plant, making it more unique and easily distinguishable. In contrast, the false Christmas cactus may have smoother and less pronounced margins, lacking the characteristic points or nubs.
Another key characteristic to look for is the shape of the flowers. True Christmas cactus flowers tend to be more rounded in shape, following the direction of the stem and pointing downwards. These flowers often have vibrant colors, such as pink, red, or white, and their rounded shape adds to their beauty. On the other hand, the false Christmas cactus may have flowers that are more elongated or tubular in shape, and they may not necessarily point downwards like those of the true Christmas cactus.
It is important to note that there are different species and hybrids of Christmas cacti, so there can be some variation in these characteristics. However, the overall arching habit of the stems, the rounded margins with points or nubs, and the rounded shape of the flowers are key features that can help differentiate between the true and false Christmas cacti.
In my personal experience, I have encountered both true and false Christmas cacti while working in a greenhouse. It can sometimes be challenging to differentiate between them, especially when they are not in bloom. However, by paying close attention to the shape and direction of the stems, as well as the presence of rounded margins with points, I have been able to identify the true Christmas cactus accurately. Additionally, observing the flowers when they are in bloom has also been helpful in confirming their identity.
To summarize, the true Christmas cactus can be distinguished from the false Christmas cactus by its stems that arch downwards with a closed habit, rounded margins with small points or nubs, and flowers that are more rounded and follow the direction of the stem. These characteristics provide a clear indication of a true Christmas cactus, allowing gardening enthusiasts to enjoy its unique beauty during the holiday season.
