Lavender 

    Lavender is a type of plant found on almost all continents. It has a purplish color. It has a color named after it, called lavender. Its Latin and scientific is Lavandula.

    Lavenders are very popular among gardeners. Sometimes their petals are dried and sealed in pounces for good scent, and sometimes put inside clothes to prevent moths who can damage the clothes.

    Lavender are also used in cake decorating because the flowers can become candied. Sometime they are used in flavoring baked goods and chocolate desserts, and sometimes they use it to make a very delicious "lavender sugar".  Lavender flowers are also used to make tea. The French make lavender syrup, which is used to make lavender scones and lavender marshmallows.

    Lavenders are sometimes put in medicine too and sometimes to prevent infection- such as lavender oil, that was used in World War 1 to disinfect walls and floors of the hospital. As the folk wisdom says, lavender tea helps you relax before bed time. Lavender also is very helpful when applied to insect bite.

    Sometimes, dried petals of lavender are used to throw confetti at a wedding.
