These are all CHRISTMAS plants. No Hannukah bushes. No Kwanzaa jungle vines. Why call them “Holiday” plants?!
I’ve seen Christmas cacti also referred to as Thanksgiving cacti.
Poinsettias will last year-round but getting them to bloom again requires putting them in a dark space while still providing water. They are a nice green plant and can even be planted outside in summer. After all, they’re easy enough to find again with the red bracts showing off for Christmas.
