UNUSUAL FORMS: a class of daylilies based exclusively on form, not on color or color patterns, and not on petal length. Any flower that meets the Spider measurement criteria cannot be considered a UF.
There are 3 types of UF flowers, based on their tepal (petal and sepal) shapes:
1. CRISPATES: a flowers whose petals twist, fold or curl.
a. PINCHED CRISPATE - floral segments have sharp folds giving a pinched or folded effect. Example: PUPPET LADY JOSHUA COBB
b. TWISTED/CURLED CRISPATE - floral segments present a corkscrew or pnwheel effect. Example: BOO WEBSTER WIND FRILLS
c. QUILLED CRISPATE - floral segments turn on themselves to form a tubular shape.
2. CASCADES: Narrow florals segments with pronounced curling or cascading
(like in a waterfall) segments which revolve upon themselves in the manner of a wood
3. SPATULATES: Floral segments markedly wider at the end like a kitchen spatula
One of the interesting features of Unusual Forms is that they often combine more than one feature, such as twisting and pinching crispation. In addition, the flowers often look different from day to day, depending on the amount of crispation that is displayed on any given day.
