There are both edible and non-edible varieties of flowers in existence. Some vegetables, such as cauliflower and broccoli, are technically classified as flowers. It is also common to add flower petals into salads, or to use attractive and colorful petals as decoration on a plate. Some popular examples of edible flowers include carnations, lavender, gardenias and peonies. However, on the contrary there are also many non-edible flowers that are actually poisonous if consumed.


Anemone is also commonly known as thimbleweed, windflower and pasqueflower. Anemone is a perennial herb that comes in many colors, including yellowish-green, white, purple and red. The flowers originate in Asia, Europe and North America. All parts of the anemone, when fresh, are poisonous and therefore non-edible. If vast amounts of anemone are consumed, a person can experience severe mouth pain.


Agapanthus is also known as the African lily, African blue lily and flower of love. It is part of the Agapanthaceae family. The flowers of the Agapanthus range in color from purple to blue and white.
