What do you grow that has medicinal value? So far I've grown the basics such as chamomile, peppermint, echinacea, aloe vera and such. But this coming season I'm hoping to branch out into the more exotic plants. Astragalus is next on my list. If you haven't already tried growing chamomile, it's incredibly easy to grow and the flowers are beautiful. It's a good one to start with if you're interested in medicinal plants.
