I love Dogwoods. This one is outside Loring Arena (ice skating) in Framingham, Massachusetts. I think the blooms are lovely and are a beautiful symbol of spring.
Some people also see Dogwoods as a symbol of the crucifixion of Jesus Christ. The four white bracts represent the hands and feet of Christ. Each is marked with a hole and blood. The flower in the center of the bracts represents the crown of thorns.
