Tolerant of summer heat and humidity.

Noteworthy Characteristics

Hemerocallis minor is a dwarf species daylily that makes a good parent for hybridizing dwarf or miniature daylilies. Yellow flowers are borne on naked stems (scapes) up to 18" tall which grow well above a lower-growing clump of arching, linear, narrow leaves. Individual flowers open for one day. Species is sometimes commonly called grass-leaved daylily.

Genus name comes from the Greek words hemera meaning day and kallos meaning beauty as each flower lasts but one day.

Specific epithet means small.


No serious problems. Daylilies are extremely adaptable perennials. They are easy to grow, quick to multiply and virtually pest free.


Provides color and contrast to the perennial border when grown in clumps or when massed over larger areas. Also appropriate for the rock garden. The fountain-like leaves provide elegant foliage, color and texture for the garden when the flowers are not in bloom. Daylilies can crowd out weeds and form a verdant ground cover.
