The Victorians often gave sweet peas to thank hosts after being hosted to show their appreciation for a wonderful time. 

The fragrance was believed to brighten the home.

In France, they are given to brides to ward off negativity and wish them luck on their wedding day. 

Ancient Greek nymphs were said to be able to turn themselves into peonies to avoid being seen by humans. The peony flower has many petals, and protect their centres even once reaching full bloom. 

They seem the showiest of flowers to me! 

Poppies are used to make opium sedatives so often linked with sleep. 

In Greek mythology, poppies grew in the land of the dead + linked with Persephone who was the queen of the underworld.

The poppy for many of us is linked to remembrance day and the military after they flourished on world war one battlefields.
