Plants

More than 60 different species of plants are known to grow on Dokdo. Most of them are herbaceous plants that can grow on the islet's thin soil deposits, but a number of woody plants also grow there, including spindle trees, giant knotweeds, Ulleungdo honeysuckles, camellias, broad-leaf olives, big cone pines, rubus phoenicolasius maxim, and asclepias.
Spindle trees, the oldest plant species found on the island, were designated as Natural Monument No. 538 on October 5th, 2012. They grow in Dokdo, the country's easternmost point, for more than 100 years, and thus people attach symbolic value to them.
