Anthophobia (from Greek roots anthos, flower, and phobos, fear) is an abnormal, irrational, intense and persistent fear of flowers. Though sufferers generally understand that they face no threat from flowers, they invariably experience anxiety at the sight or thought of them. There is no specific flower which causes this fear. Any genus or species of flowers can instil fear, so can any flower part such as a petal or stem.
Anthophobia is usually caused by traumatic experience in the past that is linked emotionally to flowers. Many times, anthophobia is not caused by an actual event but triggered by harmless events at a very young age, like watching movies and TV, or perhaps seeing someone else getting hurt like being pricked with the thorn of a rose or another flower.
Another source of this fear is an allergic reaction to a certain flower thus causing the person to avoid flowers in general, and be scared even at the mere thought of flowers. In those who believe in Tarot Cards, they are aware that the Grim Reaper which symbolizes death carries a white rose and any thought of this particular flower can cause them great unease.
Symptoms include dizziness, palpitations, nausea, restlessness when presented with a flower. They might avoid events that they know will have flowers such as weddings or funerals, and will avoid going to the garden.
Treatment involves psychotherapy and is usually enough for most people. Medications are rarely needed.
