Lycoris Research Review
Lycoris specialist Mark Roh
For more than 20 years United States Agricultural Research Services horticulturist Mark Roh has been intrigued by the origins and habitats of the exotic and beautiful Lycoris. Although various Lycoris species have been grown as ornamentals in China, Korea, and Japan for many centuries, only two species are readily available in the West: L. squamigera and L. radiata. They, and the rarer L. incarnata, L. chejuensis, and L. flavescens, are maintained at the U.S. National Arboretum (USNA), in Washington, D.C., and in Beltsville, Maryland.
In 1984, Roh collected several unidentified Lycoris species from Anduck Valley, on Korea’s Jeju Island. This sub-tropical area hosts about 4,000 species of plants. Then in 1998, more Lycoris species were collected in Japan, Korea, and China. DNA molecular markers and chromosome studies proved that some of the unidentified Lycoris collected from Anduck Valley were L. incarnata, a species previously known to be native only to China. It is possible that this accession was brought from China to Korea by bulb collectors, but no record of that can be found.
