Helleborus 'Dashing Groomsmen' is a selection from Hans Hanson's Wedding Party series. It has large double slate gray to dark purple flowers. Like all memebers of this series it is a strong grower with displays of large numbers of blossoms per plant, and rich flower colours.
Despite their reputation of being hard to grow, Hellebores are not fussy plants. Give them rich, moist organic soil and shade from hot afternoon sun during the summer. They can even tolerate short periods of drought. Hellebores are evergreen so, after the plants are actively growing, trim back any foliage that has been damaged in the winter. Hellebores are poisonous so do not consume any part of the plant.
