A more recent registration class based on form, its definition states: The Unusual Form class is based exclusively on form, not on color or color patterns. The flower must have distinctive petal or sepal shapes, or a combination of both on all three petals or all three sepals. It includes three basic sub forms: crispate, cascade and spatulate. The crispate sub form is further defined below.
Definition: Pinching – Floral segments which have sharp folds giving a pinched or folded effect. See below for pinched crispate illustration.
Here are two examples of a Pinched Crispate. Petals are distinctly pinched or folded.
Definition: floral segments which present a corkscrew or pinwheel effect. See below for twisted crispate illustration.
Definition: floral segments which turn upon themselves along their length to form a tubular shape. See below for quilled crispate illustration.
Definition: floral segments with narrow curling or cascading segments, resembling wood shavings) See below for cascade illustration.
Definition: (segments markedly wider at the end like a kitchen spatula.) See below for spatulate illustration.
The purpose of this class is to recognize unusual forms whose length-to-width ratio puts them outside the Spider classifications.
The AHS makes available a list of officially registered unusual form daylilies each year. It can be downloaded free from the online database. Only daylilies that appear on this official list are eligible for entry in the unusual form section of the show.
