At the time of the crucifixion, the dogwood had reached the size of the mighty oak tree. So strong and firm was the wood that it was chosen as the timber for Jesus' cross.
To be used for such a cruel purpose greatly distressed the dogwood. While nailed upon it, Jesus sensed this, and in his compassion said. "Because of your pity for my suffering, never again shall the dogwood tree grow large enough to be used for a cross. Henceforth, it shall be slender, bent, and twisted, and its blossoms shall be in the form of a cross–two long and two short petals.
"In the center of the outer edge of each petal will be the print of nails. In the center of the flower, stained with blood, will be a crown of thorns so that all who see it will remember."
