Hardy Hemerocallis, Paeonia and Lilium |
Abbreviations & Definitions

| Plant Units | |
| Daylilies (all units are blooming size) | Peonies |
| SF=single fan division (one growing point with root system) | Basic Size=small plant, may take a year or two of growth to bloom. Tree Peony graft of 1 or 2 years of age. |
| DF=double fan division (two growing points with a root system) | Select Size=standard size plant. Tree Peony graft is generally 3 to 4 years of age. |
| CL=clump of fans (three or more growing points with a root system) | STD root=herbaceous or intersectional root with 3 to 5 eyes with a root system that will support the growth from existing eyes. Some hybrids produce lesser numbers of eyes per division, others more. Our divisions should bloom within a year or two. |
| Plant and Flower Key | |
| YGT=yellow and then green throat of flower | Single=flower with a single row of petals surrounding central reproductive organs |
| GT=green throat of flower (tends to enhance other colors) | Semi-double=flower with double row of petals or more, but center of flower is still exposed after opening |
| HBC=high bud count | Double=flower that is completely filled with petals and central reproductive parts are hidden after opening |
| H?=may not be hardy in our climate or needs winter protection | Anthers and Filaments=male part of flower, usually yellow (pollen) |
| Picotee=small band of color around the edge of petals | |
| Edge=refers to a colored border that may have 1 or more colors in it and can have different ruffling structures (bubbled look, toothy look, ruffled look, pie crust look, etc...) | Flare=a dark area at the base of each petal on the flower. Rockii and its hybridize have large dark flares. |
| Watermark= and area of lighter color within the flower (usually just above the throat), which appears to have been stained by water | |
| Eye or eyezone: an area above the throat that has a different color than the rest of the flower | Single flower=a flower that generally will have one or two rows of petals and the reproductive organs are easily visible. |
| Self=The entire flower is the same color | |
| Polychrome=flower is a blend of colors with verying intensities of gold, yellow, cream and pink | Semi-double=a flower that generally has 3 or more rows of petals. These can appear quite close to double, but generally the reproductive organs are still visible upon opening. |
| Season of bloom=period of time during daylily bloom season in which a cultivar blooms. This is not determined by date, but is rather a comparison of different cultivar's blooming periods. In Wisconsin most EM (Early Midseason) and M (Midseason) bloomers have little, if any difference in the time they bloom during the season. ML (Midseason Late) cultivars often bloom a week or two after the other begin bloom and L (late) not long after. Bloom seasons are more compressed as on travels further north. VL (Very Late) occurs as ML plants finish up. | |
| Diploid=normal set of chromosomes | Double=numerous rows of petals obscure the reproductive organs of the flower. Usually only the petals are visible throughout. |
| Tetraploid=a double set of chromosomes, generally produces larger plants and flowers (not always) | |
| UF= Unusual Form. Spiders, crispate, cascading, spatulate, recurving, pinched, etc... See AHS UF page. | Notch=petals that appear to have been cut at the very outer edge. |
| Scape=the stem which holds the flowers on a daylily. | Pollen= able to fertilize female cells successfully Seed or Pod= able to produce viable seed |
| Dormant=foliage type that is hardy in our climate, plants produce dormant buds during winter (beware, many southern cultivars are now being registered as dormant and are not in our climate) | Carpels=seed carrying vessels of a peony flower |
| Evergreen=foliage type that continually grows and is not generally recommended for our climate (semi-evergreen is a synonym for evergreen in Wisconsin) | Stigma=female receptive organ that rests at the top of each carpel. Often colorful accents to the flower. |
| Branching=the number of secondary stems that are growing from the primary stem arising from the plant. Branching typically allows more than one flower to open at once per stem. When hybridizers list 5 or more branches they are likely counting anything that resembles a branch, including v's at the top of scapes (difficult to consider a branch). |
Fertility= ability to produce male and female cells that can
in turn produce offspring. |
| Lateral branching=branches produced from nodes along the stem. These branches tend to be longer and produce a fuller scape. This what we consider true branching and is what we count for registration purposes. | AGLH=Advanced Generation Lutea Hybrid (at least one parent is of hybrid origin and contains P. lutea as a parent). |
| Top branching=branches produced at the top of a scape. These tend to produce many flowers at the top of a scape (we don't count these as branches on Solaris Introductions). | |
