It's really fun growing plants, especially when they have more than just aesthetics. You can also find and forage your own wild medicinal plants, but like i said do all the research needed. Theres thousands, and most of them are considered weeds by the unknowing eye. There are some really unique plants that don't have any look alikes and are safe for even the noobiest of people to practice with, like jewel weed for burns & rashes (especially rashes caused by poison Ivy).
