Flower gardening has the potential to become a much-loved enthusiasm, but it also has the potential to be overwhelming, particularly when one is just beginning the hobby. Inexperienced gardeners may be at a loss for where to begin because there are millions of different plant species to pick from and even more different ways to combine them.
The best option is to get started on a modest scale during the initial year, and you shouldn't be afraid to learn from your failures. You will be able to modify your garden over time by removing elements that were unsuccessful and expanding upon those that were successful. You'll eventually find a gardening aesthetic and a collection of plants that brings you joy, and the journey of figuring out what exactly those things are can be an enjoyable surprise.
This great book will tell you everything you need to know about flower gardening, from the beginning to the end.
