EARLY BLOOMING (DAYLILIES)
Having an early flowering time, typically in late June.
The outer edges of a daylily's tepals. They can be smooth, ruffled, pie crust, or picotee.
The term "evergreen" literally means ever-growing or having persistent foliage. Evergreen daylilies continue growing year-round in mild climates that do not experience below freezing temperatures in winter. Though they attempt to grow continuously in colder, northern climates, freezing temperatures interrupt their growth cycle. In very cold climates, evergreen daylilies essentially stop growing completely in the winter. In transitional climate, where the soil does not remain continuously frozen through the entire winter, evergreen daylilies may continue to sprout new growth on warmer days.
In northern gardens, evergreen foliage dieback progresses as the temperature drops. Unlike dormant daylilies, the evergreen types do not shed their foliage at a particular time. Each leaf on an evergreen fan tries to keep on growing. Usually only foliage tips show damage at first. Freeze damage subsequently causes dieback further down the leaves into the clump. Unless cut to the soil line, evergreen daylily clumps will often show green foliage for several inches above the plant crowns even in mid-winter. While the dead foliage on dormant daylilies dries out and decays over winter, freeze-damaged evergreen foliage is often mushy and slow to dry and decay. In the north, a clump of evergreen daylilies in mid-winter is a pile of greenish-brown mush.
Unlike dormant daylilies, the evergreen types do not form foliage buds on their crowns during the winter. Rather, in the spring, an evergreen daylily resumes growth from the center of its foliage stump, sloughing off any old foliage as they grow.
EXTENDED BLOOM (Daylily)
A term used to describe a daylily that remains fully open for an extended period of time, usually 16 hours or more. This characteristic is highly desirable in a cultivar.
EYE AND EYEZONE (Daylily)
A darker colored area just above the watermark on both the petals and the sepals.
The eye of a daylily is usually circular, although hybridizers have produced substantial variation in its shape, color intensity, and width in recent years.
