Stonecrop (Sedum lineare)

Japanese: マンネングサ(万年草) - マンネングサ(英語表記)Sedum lineare
Stonecrop (Sedum lineare)
A perennial plant of the Crassulaceae family. It is also called Sedum onomatopoeia (male perennial plant). It is widely distributed from Honshu, Shikoku, and Kyushu to Okinawa and southern mainland China. It grows on rocks in mountainous areas and is sometimes cultivated for decorative purposes. It is fleshy overall, with creeping stems and linear leaves about 2 cm long that taper to a blunt tip. It has an upright flower stalk 10 to 20 cm tall and three leaves in whorls. The ends of the branches branch out and yellow flowers bloom in May and June. It has five sepals and petals, and ten stamens, arranged in a double whorl of five on each side. Closely related species include Sedum uniflorum (a female evergreen plant) which has alternate leaves, and Sedum uniflorum, which grows in Okinawa and other areas and has single flowers at the end of each branch. Recently, the foreign Sedum mexicanum has been spreading mainly in urban areas.
