News » 26.06.2026 - Korea's first quarantine greenhouse preserves rare plants

On the morning of the 9th, inside the "quarantine greenhouse" at the Useful Plant Propagation Center of Yongmun National Arboretum in Gyeonggi Province, three spaces were divided by transparent glass walls. In the "Phase 1 Room," seeds of five species of plants over 300 years old, brought from the Linnaeus Garden in Sweden last month, were sprouting small shoots in pots. Ko Chung-ho, a forestry researcher at the National Arboretum, said, "We collect rare plants and manage them in three phases according to their growth levels. Before mass propagation, we test whether these plants could potentially invade native ecosystems."

The "quarantine greenhouse" is a space where rare domestic and foreign plant species that have never undergone breeding are isolated and managed. According to the National Arboretum on the 15th, this is the first time a quarantine greenhouse has been established in Korea for the research and propagation of such original species.

Since these plants are not widely distributed in Korea, foreign species must be checked for potential risks, while domestic species are given special care to enhance their potential for mass propagation.

At the center, leaves, roots, and branches of rare species are cut into pieces as small as watermelon seeds to create "experimental groups," which are incubated until they can be transplanted into soil. They are then sent to the quarantine greenhouse to confirm whether foreign species could become "invasive alien species."
