I am sorry for my ignorance in advance. My wife has received this beautiful plant as a Christmas present. We love to know what it is, and more importantly, how we should take care of it to keep it alive as long as possible.Should we change its plastic pot?
First, let me assure you there is no need to apologise for 'your ignorance'; you're not the first to not know a plant name and you certainly won't be the last! That said, this is Schlumbergera truncata, a forest type cactus plant,commonly known as Christmas cactus. It's relatively easy care; this answer here, whilst it does contain some slightly irrelevant information, has care information regarding this plant /Blooming my Zygocactus houseplant
