Hacquetia epipactis
Hacquetia epipactis is a species of flowering plant of the family Apiaceae, native to moist, shady woodland habitats in Europe. The only species of its genus, it is a rhizomatous, clump-forming herbaceous perennial, growing to about 30 cm in height, with glossy green leaves which only fully develop after flowering. The flowers, appearing late winter and early spring, consist of multiple tiny yellow florets framed by lime green bracts, and carried in dense spherical umbels 4 cm in diameter. It is easy to cultivate in Plant Hardiness Zones 5 to 7 according to the United States Department of Agriculture, and looks best in a woodland setting which imitates its native habitat.
Under the synonym Sanicula epipactis this plant has gained the Royal Horticultural Society's Award of Garden Merit.
Known cultivars include the variegated ‘Thor’.
The specific name epipactis comes from a Greek word for plants thought to curdle milk.
