Can you identify this odd plant?

This plant came from Home Depot, bundled up in a hanging basket with some succulentLearn how to grow and care for succulent plants at Houseplant411.coms and other plants that like arid conditions. It is different. Can you help me find some info on this please?

It has red/green stems and each stem has three little red leaves. I transplanted it into a big pot and it has taken off in the
Hot Texas sun. Any info would be appreciated.

Hi John.

Your plant is called a Pencil Cactus. A Pencil Cactus, Euphorbia tirucalli, is not a cactus plant at all but rather a member of the Euphorbia family, like a Poinsettia.

A Pencil Cactus Plant grows quickly and can reach a height of 10ft-15ft. outdoors and up to 6 feet in an indoor container.  Although this is an easy care houseplant that just needs some bright light and a little bit of water to do well, it does have a downside it’s a poisonous plant and should be kept away from pets and children.
