I recently got this plant and I looked up on internet but couldn't find one. I don't know anything about this plant and so my question. What plant is this? Corn Plant or Janet Craig or none?
Could be a young Janet Craig, but also looks like a leggy Green Jewel to me (its more compact). All fall under Dracaena anyway, so if you Google image search Dracaena, I'm sure you'll find a match rather quickly. All have similar care requirements; moderate exposure, moderate moisture. Too much water is quickly displayed by yellowing tips. Very hardy and one of my favorite houseplants due to the fact.
Edit: This site may help you pin down what you have. It actually looks like the Elegance Cane they have pictured: MiamiTropicalPlants.com

I asked the question on another garden forum, and they told me it's Dracaena Reflexa. After some google search, I found it to be Pleomele - Dracaena Reflexa.
