You may be unsure about which flower type or color is appropriate for each occasion. Almost every flower has a historical sentiment attached to it that conveys a message to the recipient or guests at an event like a wedding.
A tansy flower, for example, is a member of the daisy family with happy button-like heads, but to some, it means you're sending "hostile thoughts," and “health and immortality” while to others, it means you're sending "positive thoughts". These meanings are taken from a variety of sources, ranging from the Bible to Shakespeare's words, and floral symbology has developed over the centuries.
