  According to Kathleen Karlsen of Living Arts Originals, the use of flowers as symbols for human characteristics began in ancient times. Flowers and plants were often associated with a god or goddess, and during the Renaissance it became the practice for artists to add these plants to their paintings to symbolize the characteristics attributed to a particular deity. During the Victorian era, the idea of using "the language of the flowers" to express one's feelings became very popular, and this practice is still in use today.
  
  

Pimpernel

• The Scarlet Pimpernel (Anagallis arvensis) is a tiny wildflower of the lily family. It symbolizes change, particularly a major life change.
  
  

Heather

• Heather (any plant from the family Ericaceae) is a sturdy flowering shrub that is covered with feathery lavender or white bloom in the spring. Heather symbolizes transformative change, or something growing from the mundane to the extraordinary.
  
  

Lilac

Black Rose

Daffodil

• The common daffodil (Narcissus sylvestrus) is one of the first flowers to bloom in the spring, often poking its green shoots through the snow. It symbolizes the change of seasons, the triumph of new hope over despair.
  
  

Delphinium
