Step 1: Materials
In the image you can see all of these materials, the native plant seed in question being the seed pod of a Trumpet Vine. When the seed pod is split appart you can find dozens of small paperlike seeds inside. A good time to look for any native plant seed is late summer or fall. If you cannot find any in your area you may inquire at a garden store about their native plant seeds, or order native plant seeds online.
When choosing a plant be mindful of how "hardy" it is, meaning how well it resists draught or over watering. The goal is to find a very hardy plant so that it will flourish no matter the circumstance
