(Color Patterns In Daylilies By Mie Restait 
HE NUMBER of the distinctive pigments, their quality or nature, 
and their distribution in the face of the open flower are the main 
features of significance in defining the classes of color patterns in the 
flowers of daylilies. 
There are two principal classes of pigments in the tissues of the flowers 
of daylilies: (1) the plastid pigments which give the green, the yellow and 
the orange color effects and (2) the sap pigments or anthocyanins which 
are some shade of red. The plastid pigments are chiefly sub-epidermal 
and hence mostly confined to the inner tissues; the sap colors are most 
strongly developed in the outer or epidermal layer of cells. Thus the 
effect in any area of the face of the flower may involve only one of the 
two kinds of pigments or be the combined effect of one over the other. 
There are many gradations in color values from green to yellow and 
orange and in the shades or tones of yellow and of orange. For the red- 
colored pigment there is also much diversity 1n shade and intensity. 
For the following outline of color patterns there has been consideration 
of the species of Hemerocallis, the large number of named horticultural 
clones, and the numerous hybrid seedlings that have been grown at the 
New York Botanical Garden. 
When there is more than one distinct shade of pigmentation the tendency 
is for the distribution to be either concentric or radial. One of these 
distributions may dominate in a pattern but both may be strongly in 
evidence in the same flower. 
At the present time the writer does not wish to apply single names to 
each and every one of the patterns noted in the following scheme. Here 
the descriptive terms which apply to a pattern are the several names 
given for the main class, the sub-divisions, the individual pattern and the 
sub-pattern. For example, the pattern of Fig. 7 is concentric, two-toned, 
banded, and radiate. There are, of course, intergradations between various 
of the 15 patterns here described and illustrated. 
I. SELF-PATTERN. The entire face of 
the flower is of one color. 
One-toned; Fig. 1. The one-toned pat- 
tern is usually some shade of yellow or 
orange and hence the pigments are plastid 
in origin. Frequently the extreme throat 
is somewhat green, but when this be- 
comes distinct in contrast to either yel- 
low or orange in the outer part of the 
perianth the pattern becomes concentric. 
II. CONCENTRIC PATTERNS may be ar- 
ranged into four groups and these further 
divided into at least 9 different pattern 
types or individual patterns. 
A. Semi two-toned. The distribution 
of one pigment or the combination of 
two pigments is such that there is a 
gradual but rather uniformly concentric 
change in the intensity of one dominant 
color. 
Centric; Fig. 2. In this the shade of 
coloring is most intense in the extreme 
throat of the flower. Certain seedlings 
have this pattern in a coloring dominated 
by the sap pigments. This particular pat- 
tern is new and unusual for Hemero- 
calhs. 
Distal; Fig. 3. In this pattern the shade 
of color becomes more intense toward
