These plants are a close relative to the traditional banana (Musa), but they are not true bananas and are prized for the reddish coloration. They also differ in their growth habit: Ensete do not sucker like bananas, so don't form large clumps over time.
Like many tropical plants, these can be successfully wintered inside, although they will likely stop growing or slow down. In the summer, they appreciate being moved outside, where they can get adequate sun, which is important for their full leaf coloration. Like bananas, these plants are rapid growers and love plenty of moisture, fertilizer, heat, and sunlight—the more you can provide for these conditions, the better your plants will look.
