The Crown of Thorns is a succulent plant native to Madagascar. It has thick, spiny stems and clusters of small, colorful flowers. The plant is drought-tolerant and can grow in various soil types. It is often cultivated as an ornamental plant, but it can also be invasive and toxic. The sap of the plant contains latex and irritants that can cause skin and eye irritation, and ingestion can result in vomiting and diarrhea. The plant is also known for its association with the biblical legend of the crown of thorns worn by Jesus during his crucifixion.

Q. What do “circa” and “in training” mean?

A. The circa date is roughly the year when the tree sprouted from its seed. The in training date is the year that it started being “trained” as a bonsai, which is to direct the growth of the tree usually by bending, pruning, and wiring its branches into a desired direction or shape.
