Other ways to distinguish between the two plants utilize flowering time and floral morphology. As you could probably deduce from the common names of these plants, Christmas cacti flower around the Christmas season in the northern hemisphere. Consequently, Thanksgiving cacti flower six weeks earlier, approximately around the Thanksgiving holiday. What causes the difference in the flowering time of these two species if they are so closely related? Flower induction in both cacti is a photoperiodic response. These plants initiate flowers in response to the shortening days of summer and fall and are termed short-day plants. The critical photoperiod for a short day plants is the length of day (hours of light) that when day length is equal to or shorter than this length flowering of the plant occurs. For example a short day plant with a critical photoperiod of twelve hours will flower when the days are twelve hours or shorter. Thanksgiving cacti have a longer critical photoperiod for flower induction (more hours of light), with flowers initiating under the typical daylengths experienced in late summer and early fall, while Christmas cacti have a shorter critical photoperiod that does not occur until later into fall.

In addition to flowering time, the morphology of flowers can help distinguish between the two types of plants. The anthers, the pollen-bearing parts of flowers, are purplish-brown for the Christmas cactus while the Thanksgiving cactus anthers are yellow. Also, the ovaries in the flower of Christmas cacti are ribbed while Thanksgiving cacti have a smoother appearance.


Holiday cacti are easy plants for home gardeners to grow. For starters, propagation of these plants is easy. The first step is to find a suitable container for growing a plant. A four inch pot is a good size for a starter plant. Next, fill it with a loosely drained medium such as the general soilless (peat-based) houseplant mix that is readily available at garden centers and home improvement stores. For starting plant material remove three or four individual mature segments (phylloclades) at least one inch in length from a larger plant (if you have a friend with a really great flowering holiday cacti, now is the time to butter them up!). One can also use cuttings involving not only a single phyloclade, but also a couple of them piggybacked as a cutting. These phylloclades may be stuck directly into the moistened medium no deeper than half of the length of the segment. To increase the success and to speed up rooting, place the pot inside a large, clear plastic bag such as a one gallon Ziplock® bag and seal almost completely shut. This will increase the humidity of the rooting environment for the phylloclades and allow for a little gas exchange. Place this on a sunny windowsill and water to maintain a moist, but not soggy, medium. The rooting process may take a while, but don’t worry- these succulents are resilient.

Sounds like you will be traveling...

I suggest you have a live flower sent to their home to arrive just before you get there... something like an azalea or a Thanksgiving cactus plant, or a Christmas Cactus plant.
While there, I recommend you be very active in helping prepare meals, serve and clean up after the meals.
Offer to do things like peeling the potatoes, set the table, etc.
Since you are going to be there for 4 days, offer to run the vacuum before guests arrive, etc.
Offer to make quick trips to the grocery store as you see the need.
If there are children in the family, help entertain the children to give their parents a break
