Dracaena (Dracaena marginata 'Ray of Sunshine') will color your world with bright yellow stripes of joy running down his slender leaves. He looks like a tree of sorts and has the leaf shape of a palm, but he is a Dracaena. Give him your best seat in the house and raise the shades so he can get some indirect, bright light to match his colored leaves. He'll top out at 6-10 feet tall, so give him plenty of headspace.
