I am a succulent with a distinctive geometric pattern and can reproduce by creating small 'pups' around my base. I'm often confused with a similar plant, but I lack the sharp teeth along my leaves and my flowers are a vibrant, tubular shape. What am I?

1. I store water in my leaves, which are usually thick and fleshy.
2. My leaves spiral outward in a rosette shape.
3. I am native to South Africa.
4. I'm popularly used in indoor decorative displays.
