Hydrangeas symbolize heartfelt emotions; they can be used to express gratitude for being understood, or - on a less lovely note - heartlessness.
Rose meanings vary according to color. On the whole, they symbolize deep love, concentration, intelligence, balance, and passion. They can also send a message of healing, rejuvenation and courage.
Tulips signify fame or a declaration of love.
Poppies symbolize beauty, ::magic::, consolation, fertility and eternal life. They can also denote sleep and repose.
Ranunculus symbolize radiant charm.
Thistles symbolize nobility
Peonies symbolize bashfulness, compassion, a happy life, happy marriage, good health and prosperity, indignation, or shame (mixed messages much?).
Anemones can either indicate fading hope and a feeling of having been forsaken, or anticipation.
These are some of my very favorites flowers.
What are yours (and have you ever looked up their supposed symbolism)? :-)
