SELF - the simplest pattern: petals and sepals are all the same, single color.

BLEND - the petals and sepals are a blend of two or more colors.

POLYCHROME - an intermingling of three or more colors.

BITONE - petals and sepals differ in shade or intensity of the same basic color.

BICOLOR - petals and sepals are of different colors.

EYED - the flower has a zone of different color, or a darker shade of the same color, located between the throat and the tips of the petals and sepals, i.e. in the center of the entire flower. The term 'eyezone' is often abbreviated as 'EZ'.

BAND - an eye zone that occurs only on the petals.

HALO - an eye zone that is faint or only lightly visible.

WATERMARK - an eye zone that is lighter than the petal color.

PICOTEE or EDGE - usually an outer petal of 1/4" or 1/2" edge of a lighter, or different color.

DIAMOND-DUSTED - tiny crystals in the flower's cells reflect light/sun.

STIPPLED - looks like someone spray-painted petals with dots of slightly different shade of color. Unusual. Not necessarily desirable and not universally sought after.

MIDRIB - the center vein running lengthwise through each petal is a different color from that of the petal itself.

THROAT - the very center or core of the flower may have a green or other color which is different from the flower.


Daylilies come in different shapes and sizes, as well as in different colors and color patterns.

Some forms are officially recognized, and others merely fall into categories that people informally use to describe their shape.

Terms such as 'round' and 'flat' are self-explanatory, as are 'triangular.'

'Double' can be described as a daylily with additional flower segments that tend to either set right on top of the main petals and sepals ("hose-in-hose") or are formed out of converted stamens and tend to jumble in varying degrees. The former looks as if one flower were laid on top of another. The latter tend to look like a peony flower. See below for the latter, which is the more typical.

Doubles, which have extra flower segments should not be confused with 'polytepal' flowers, which simply have more than the usual three petals and three sepals. Much like a four-leaf clover is unusual, so is a four-petal daylily. However there are numerous hybridizers working with those daylilies that tend to consistently produce more than three petals and three sepals in the hopes of creating more polytepal daylilies that bloom 100% polytepal. In addition to 4-segment polytepals, I've even seen five-petal flowers.

Many newer daylilies do not fit conveniently in existing categories, so a new 'class' of "Unusual Forms" has been created as its own distinct category. These Unusual Forms are often affectionately abbreviated as "UFO."

UFO daylilies can even be further subdivided into three categories: Crispates, Cascades, and Spatulates. And Crispates into three types: Pinched, Twisted, and Quilled. Most Crispates bloom in different poses every day, and even bloom differently on the same scape making them Variable Crispates.

Pinched Crispate: Floral segments with sharp folds giving a pinched or folded effect.

Twisted Crispates: Floral segments which present a corkscrew or pinwheel effect.

Cascade: Narrow floral segments with pronounced curling or cascading, which revolve upon themselves in the manner of a wood shaving.

Spatulate: Floral segments are markedly wider at the end like a kitchen spatula.

(These descriptions and the UFO images were contributed by Bob Schwarz, one of the most ardent UFO proponents. These UFO daylilies are tetraploid and are from among his seedlings.)
