Hemerocallis minor has long been a favorite in this garden. It's usually the earliest of the day lilies to bloom, and its comparatively small stature makes it a nice companion for the earliest, shorter bearded irises. The flowers are sweetly scented, and the clear yellow flowers are carried on gently arching scapes. As a result, the flowers are often only six or eight inches above ground.
This is not a floriferous species: generally there are only four to six blooms per scape. Until it blooms, its fine foliage might suggest a coarse grass.
