Blooming pencil cactus
Never seen this before! Also recently learned a couple other things about this plant: Despite the name it's actually a euphorbia, a succulent, and not a cactus. If it starts off trailing (like mine) it will stay that way, versus growing into a tall plant. The clear sap that pencils produce (the little bubbles on the stems) is toxic and can give you a bad rash.
