Definitions from the American Daylily Society:
- Ruffled - Term used to describe the tissue on a segment's edges (petals/sepals), resulting in a wavy appearance. Ruffling may be very loose and deep or tightly compressed.
- Angel Wings - A type of ruffling on the edge of petals that causes a portion of the petal to fold forward showing the back of the petal.
- Owl Ears - Observed when a ruffled daylily is so strongly recurved that when viewed from the front the edges of the daylily protrude like ears on a Great Horned Owl.
- Owl Wings - A type of ruffling on the edge of petals that causes a portion of the petal edges to fold backward.
- Pie Crust - A descriptor used for ruffles, usually indicating that the ruffles are very evenly spaced and evenly alternate between raised and lowered petal edges, like a decorative pie crust.
