First opened in June 2004, Yanggu Eco-Botanical Garden was built on a total area of 189,141㎡. 3.1 billion Korean won (approximately 3 million USD) was spent on the construction and it was built to be developed into a South and North Korean ecosystem restoration center. Located in the northernmost region of South Korea, it houses more than 400 rare plants including plants that are Korean native species and protected by Korean Ministry of Environment. The garden is divided into six parts by their features including Botanical garden, Natural forest, and facilities zone. In the Botanical garden, rare plants such as northern native plants and alpine plants that are naturally grown in the demilitarized zone (DMZ) and Yanggu area are displayed in one place. There are also walking trails, a medicinal plants exhibition hall, a plant nursery, and a greenhouse. In order to supplement the shortcomings of the botanical garden, which is a static atmosphere, a mountain stream zone and wetlands zone were prepared to provide people with the chance to enjoy the pleasant sound of running water. * Total area: 189,141㎡ * Plants that are Korean native species and protected by Korean Ministry of Environment in the garden: Geumgang Chorongkkot (금강초롱꽃 (Diamond bluebell, scientific name: Hanabusaya asiatica Nakai) Kkaengkkaengipul 깽깽이풀 (Asian Twin Leaf, scientific name: Jeffersonia dubia) Gaeneusam 개누삼 (scientific name: Echinosophora koreensi) * Other rare plants in the garden: Sankkoripul 산꼬리풀 (scientific name: Veronica rotunda var. subintegra) Jebidongjakkot 제비동자꽃 (scientific name: Lychnis wilfordii) Somdari 솜다리 (scientific name: Leontopodium coreanum) Geummatari 금마타리 (scientific name: Patrinia saniculaefolia) Norangmunuibutkkot 노랑무늬붓꽃 (Korean Iris, scientific name: Iris odaesanensis) Haneulmaebaltop 하늘매발톱 (scientific name: Aquilegia flabellata var. pumila) Solchekkot 솔체꽃 (Mansenese morning bridge, scientific name: Scabiosa Scabiosa mansenensis) Byeongjohoepul 병조회풀 (scientific name: Clematis heracleifolis)
