Daylily Terms and Abbreviations

In this section the descriptive terms and abbreviations used to describe clones in this publication are briefly explained.

Terminology and Abbreviations
Used in Describing Clones Prior to July 1, 1957


Height of scape is expressed in inches as it performs in the originator’s garden.


  • EE – extra early
  • E – early
  • EM – early midseason
  • MLa – late midseason
  • La – late
  • LVa – very late
  • Re – remontant, or reblooms


Fragrance is lacking unless indicated as below:

  • fr. – fragrant
  • – very fragrant


Day-blooming unless indicated otherwise

  • diu. – day-blooming
  • noc. – night-blooming
  • ext. – extended blooming, flowers remain open 16 hours or more


  • ev. – evergreen (continuous growth)
  • semi-ev. – semi-evergreen, or intermediate between the two extremes
  • dor. (de.) – dormant (deciduous), discontinuous growth or dormant in winter


Two methods of color descriptions are used in this publication. The clones registered before and including 1953 are described by the use of symbols or abbreviations. Those registered since 1953 are described in words, using the originator’s own description. Both of these systems give only a general idea as to the color and are not intended to give an elaborated description such as will usually be found in the introducer’s catalog. The clones registered since 1953 are in simple color terms and need no explanation. The section below applies only to those registered prior to this change.

The color patterns are indicated by three numbers:

  • 1 represents a self;
  • 2 represents markings, rays, veins, halos, spots, borders or shades of same color (bitones), or different hues (polychromes or pastels);
  • 3 represents bicolors which have petals of a definitely different color from that of the sepals.

In lieu of more definite pattern numbers, the following letters are added where required:

  • P (Polychrome) to indicate pastel, blend, or a combination of colors. The color letter will indicate the overall impression at a distance.
  • S (Spot) indicates a definite spot or band
  • H (Halo) indicates a darker area not of sufficient depth to be called spotted or banded.

The following daylily cultivars are illustrations:

‘Hyperion’ – GYL1; Green-Yellow, Light, self pattern.
‘Bicolor’ – ROM/YOL3; Red-Orange, Medium petals; Yellow-Orange light sepals. 3 indicates the color pattern, which is bicolor.
‘August Pioneer’ – YOM2-P; Yellow-Orange, Medium; 2-P indicates it is shaded in Polychrome.
‘Bertrand Farr’ – ORL2-P; Orange-Red, light, 2 indicates the veins and -P that it is a Polychrome.
‘Baronet’ – ORM1; Orange-Red, Medium, self.
‘Purple Waters’ – VRM2-H; Violet-Red, Medium; 2 for veins, -H for Halo.

The following colors and abbreviations have been used:

  • B: blue
  • D: dark
  • L: light or pale
  • M: medium
  • O: orange
  • G: green
  • R: red
  • V: violet
  • Y: yellow
  • W: white
  • S: spot or eyezone
