The flowers, which grow in large, drooping clusters, are light purple and bloom in May.The Japanese wistarias at Oryu-ri are four, and pair of trees grow in a group.
The trees are 17m tall and have girths of 24cm, 28cm, 172cm, and 60cm respectively.
They stand beside a small brook in Oryu-ri, and they twine around a nettle tree which grows beside them.Because the king enjoyed hunting with his subjects at this place, it was called Yongnim(Dragon Forest - A dragon stands for a king).
The wistarias here were called Yongdeung(Dragon Wistaria), which meant wistarias in Yongnim.
In addition, they were also called Yongdeung because the thick branches looked like a dragon which was twisting around a tree.
There is an interesting story about these trees.
If the dried flowers of these trees are put in the pillows of newly wedded spouses, their love will be strong, and if the spouses who lose their love drink the tea of the leaves of this tree, their love will be restored.
So, many couples visit this place.
These stories result from the following legend.
In Silla Period, a peasant had two beautiful daughters.
These sisters fell in love with a man who lived next door to them.
Not until the man had to go to the battlefield, did they know they were in love with the same man.
They were such good and warm-hearted sisters that both of them decided to give him up.
One day, they heard news that the man had died in the war.
They embraced each other and cried, and they drowned themselves in a pond.
However, the man who was said to have been killed returned to be a nice Hwarang(the flower of youth in Silla Dynasty -who excelled in beauty, bravery and military arts).
When he heard the sad story of the two dead sisters, he drowned himself in the pond.
At this place, a nettle tree started growing and the wistarias twined around it.
It is said that the wistarias talk to the nettle tree about the unachieved love.
Since the Japanese wistarias at Oryu-ri have been under our ancestors' care and protection with the legend and are also valuable biologically, it is designated and protected as a natural monument.
