Dracanea. There’s all sorts out there and they get 3-5 ft tall. They’re fairly easy plants. You might have to start off in a 6 inch and wait for growth to size up. You can always stuff some grocery bags around the bottom of your bigger pot and use it for a cover until it grows into the 12x12. More on reddit.com

Ficus can look absolutely stunning when happy but are a massive headache when they aren't, as they tend to drop leaves. Make of that what you will. Yuccas and Money Trees are both reliable plants, which Yuccas more inclined towards the water-forgetting, and Money Trees more towards the water-generous. Dracaena Fragrans is a distant relative of the Yucca with a couple different types of appearances, usually being called the Mass Cane or the Corn Plant due to its leaf shape. It can get very large and is very lush and tree-like in good health, and arguably one of the easiest of the larger houseplants to work with. Dracaena Marginata is a close relative with similar care. You can also look into Palms, which for the most part are fairly easy, if sensitive about their air and water quality. Areca Palms are one of the hardiest larger palms. If your window has a lot of direct sunlight, Musa Plants(aka Bananas) and Meyer Lemon trees are available as well, with Meyer Lemons even being able to produce harvests while they are still at a manageable size.
