Yellow day lily with narrow leaves is an old traditional perennial in Finland. In Finnish it is also called the lemon lily. Day lilies are not related to lilies but they belong to the different Family. Their scientific name Hemerocallis comes from Creek and means being beautiful just for one day.
This day lily species (H. esculenta) blooms in June or July depending on its origin. It has orange-yellow slighly scented funnel-shaped flowers and one flower lasts only a day, this gives the genus its name day lily. The flowering period is however longer since new flowers appear every day. The latter part of the scientific name esculenta means eatable and daylilies have been grown as an vegetable for at least a couple of thousand years in Asia.
