Making Seed Bombs are an easy way to introduce wildflowers into your landscape in a way that allows a randomness to the placement which is an impact that you may want for wild flowers.
I would recommend starting out with using Texas Bluebonnets in your landscape, they are very easy to start, seeds are readily available and they do well with starting in the Fall which is awesome that it would be a great time to get these together and send them into your landscape for beautiful flowers in the Spring! These guys are tough like Texas, they will do well over winter and will not flower until spring, getting them out now in the Fall allows for a great show in the Spring.
First, order your Seeds, I like Baker Creek Heirloom Seed as a great source for Bluebonnet seeds as well as a variety of great seeds for your garden. When ordering Bluebonnet seeds from them, you will find them by their scientific name Lupinus texensis and can order them here.
