Elatostema umbellatum is a species of flowering plant in the nettle family (Urticaceae). It is native to Japan, where it is found from the Kantō region westward.[1] [2] Its natural habitat is in moist, deeply forested places in the mountains.[1]
It is a perennial, growing 20 to 30 cm tall. It has serrated leaves, 3 to 6 cm long, with up to 5 teeth per side. It produces umbels of small flowers from March to May.[3]
It is similar to the wider-ranging and more robust Elatostema involucratum, which has been considered a variety of Elatostema umbellatum by some authors (as E. umbellatum var. majus).[1]
