The legend of the dogwood tree comes from a poem, author unknown, about the relationship between the tree and the cross on which Jesus was crucified:
Was Jesus' cross made out of dogwood? What is the legend of the dogwood tree?
In Jesus' time, the dogwood grew
To a stately size and a lovely hue.
'Twas strong and firm, its branches interwoven.
For the cross of Christ its timbers were chosen.
Seeing the distress at this use of their wood
Christ made a promise which still holds good:
"Never again shall the dogwood grow
Large enough to be used so.
Slender and twisted, it shall be
With blossoms like the cross for all to see.
As blood stains the petals marked in brown,
The blossom's center wears a thorny crown.
All who see it will remember Me
Crucified on a cross from the dogwood tree.
Cherished and protected, this tree shall be
A reminder to all of My agony."
The dogwood is a genus of between thirty and sixty plants including shrubs, evergreens, and flowering trees. Dogwoods are most common in China, Japan, and the US, but can also be found in Eurasia, although not naturally. The wood is very hard, but, as the poem suggests, trees large enough to provide lumber for a cross are rare.
The Bible does not say what kind of wood was used for the cross. In fact, the word "cross" comes from a generic Latin term meaning a piece of wood used as a tool of execution. It's unlikely the cross was actually made from a dogwood tree, but we don't really know.
What is the passion of Christ?
What happened in the last hours before Jesus' death?
What are the last seven sayings of Christ and what do they mean?
Is the 'Suffering Servant' of Isaiah 53 a prophecy about Jesus?
Why should I believe in the resurrection of Jesus Christ?
