There are hundreds of different sedum. This one looks like ‘confused’ sedum. Used as a ground cover outdoors, they do great in dish gardens indoors. They want lots of light and not much water. Treat them as you would a cactus. Water only when the top inch of soil is dry and put it in your sunniest window.
All sedum flower, feel free to chop off the stems when they are done. Flowering is in the fall.
Rare is the houseplant that likes dry household air but this one does.
