You are a modern human being with busy schedule. You have travelled the world and admired the beautiful balconies full of flowers. You always wanted that Eden garden in the midst of the hectic everyday life. But...you killed multiple cactus plants already, and basically gave up on growing anything in your life. You are just like me then. In this case, I have one advice for you: "Geraniums!". They are easy, they are pretty and they are the perfect flower to start and expand your garden!
