To identify a daylily flower from other garden plants, it is useful to understand what sets Hemerocallis plant parts and flower characteristics apart from others in a landscape. This primer includes basic plant and daylily jargon, their meanings and explanations. While the plant characteristics are simple to grasp, beginning gardeners who have not grown the plant before should find this basic daylily information helpful.
Hemerocallis Flower Structure
The botanical name of a daylily is Hemerocallis, pronounced hem-er-o-kal' is. The basic daylily flower is a tubular shaped bloom that lasts one day and is sometimes fragrant. Daylily plants flower from summer through frost.
The petal is made of six perianth segments laid out in two rows. Looking from above a daylily bloom, a gardener will see three inner petals overlaying three outer sepals. A double flowered daylily is called a polymerous because there are more than six perianth segments.
The midrib is the center vein of a petal or sepal that runs lengthwise. In daylily-speak, the term can be important for describing part of a color or pattern in a daylily flower.
The eyezone is another term used to describe a location on the petals and sepals that has a change in color. The eyezone is above the throat and creates a visual circle around the flower.
