Whats the difference between thanksgiving and christmas cactus?

My wife says No difference....the same plant.

Agree with VickiO, bloom time = plant name

I guess it depends on what you celebrate: (lol)plants are not that discerning - they are non- religious too .The common Zygocactus referred to as "Christmas'" cactus is like the poinsettia plant . here in So California. The poinsettia can bloom outdoors in the spring. and my "Christmas" cactus blooms for me again as an "Easter" cactus The key is how many hours of darkness you expose the plant to- so you may note the "equinoxes" of winter and spring that trigger the bloom period.. They don't tolerate drying out too much , nor do they like drafts , otherwise , indoors you can celebrate any holiday you want for this great little jungle cactus . You can regulate the light exposure and have it be any bloom season you want . Have fun experimenting - I love my non- denominational zygocactus!

the only difference is that the ones purchased around thanksgiving are called thanksgiving cactus and the ones purchased around christmas are called christmas cactus.
