4. Ball Cactus (Parodia Magnifica)
This flower that starts with B is a South American native that has become very popular in recent years as an indoor cacti. It has a very unique appearance without being finicky with the care to make it a great choice for beginners.

9. Bells of Ireland (Moluccella laevis)
