Many flowering plants are edible, which allows you, the gardener, to add diversity to your table as well as your garden. As well, many of these flowering plants have very delicate flavors. The flavor of these plants is not their only value. The addition of the color in your cuisine is helpful as a positive visual stimulus. Tastefully and beautifully presented food makes people feel better on an emotional level.
When selecting edible plants for your garden and table it is important to make sure that you have chosen those plants carefully. Make sure that you have the correct species and not a close relative or different species that looks similar that may be either medicinal or toxic. Take care that you have not treated them with any chemical pesticides or herbicides.
If you have small children or developmentally disabled individuals in your home, and you use edible flowers in your culinary creations, make sure they are properly instructed not to eat random flowers, fruits, and foliage in the garden without permission as some may be poisonous.
