UNUSUAL FORM: (Official AHS Definition page here.)

A class of daylilies based exclusively on tepal form, not on color or color patterns.

An Unusual Form must typically display distinct Unusual Form characteristics on at least 3 petals or 3 sepals.

There should be minimal overlap with a "V" shaped space between 3 or more floral segments.

Unusual Form class is made up of 3 types of flowers, based exclusively on their tepal (petal and sepal) shapes. These include: Crispate, Cascade and Spatulate forms.

1. Crispates - There are three categories of Crispates:

Pinched Crispates:

Definition:
Pinching - Floral segments should show distinct sharp folds giving a pinched or folded effect..

Quilling - Floral segments turn upon themselves parallel to the midrib to form a tubular shape.

The sepals on this flower show the tubular shape along the segment that characterizes quilling.    Quirky - Couturier

Other and Combination Crispates
Definition: : Other forms of crispation, or a combination of forms appearing simultaneously on at least 3 petals or 3 sepals of the blossom.

Forms of crispation include twisting, hooking, pinching, quilling, hooking, curling and reflexing (curling back).

A blossom would be a crispate if it displayed any of these singly, or a combination of these on at least 3 petals or 3 sepals.

The example on the left shows pinching on the petals; twisting on the top petal; curling on the two top sepals, and a “pig tail” (twisted curl) on the lower sepal. There are four types of crispation on this blossom.
It would be a Crispate if only the 3 petals showed Crispate characteristics, or of only the 3 sepals showed Crispate characteristics.

The blossom on the left with 3 hooked and curled sepals is an Unusual Form.

2. Cascades

Definition: Narrow floral segments fall down beside the blossom Segments may lie nearly flat or twist.

The tepals of a Cascade should fall at least to where the segments separate at the throat of the blossom.

Unusual Forms may bloom as pure examples of their kind, but very often they combine more than one feature.

This blossom is a twisted Crispate, it is also a Cascade. It is both at the same time.
