Hemerocallis plant named ‘WF 712’
United States Patent PP26325

A new and distinct Hemerocallis cultivar named ‘WF 712’ is disclosed, characterized by its excellent landscape performance, resistance to daylily rust, orange-red flower color, with a rose pink eye, lighter pink mid rib and darker pink veining. Plants bloom early and have evergreen foliage. The new variety is a Hemerocallis, normally produced as an outdoor garden plant.

What is claimed is:

1. A new and distinct cultivar of Hemerocallis plant named ‘WF 712’ as herein illustrated and described.


Latin name of the genus and species: Hemerocallis hybrid.

Variety denomination: ‘WF 712’.


The new Hemerocallis cultivar is a product of a planned breeding program conducted by the inventor Philip Dale Westmoreland, in Southern Louisiana. The objective of the breeding program was to produce new Hemerocallis varieties with strong performance in the landscape. This includes such characteristics as clear color, repeat bloom over a long period, strong and upright flower scape, high bud count, fade resistance of blooms, foliage appeal, and maintaining plant vigor throughout the season in a general landscape environment where it may not get optimum care.

Since the advent of daylily rust, beginning in approximately 2000, caused by Puccinia hemerallidis, the top priority in the breeding program has been to develop seedlings with a high resistance to daylily rust, in addition to the previously cited characteristics. The selection process involves no application of fungicides on any cultivars in our hybridizing program. This practices results in a loss of many cultivars in the program, but is necessary to determine which varieties may be rust resistant.

All daylilies from this program are hybridized, evaluated, and multiplied in plastic nursery containers using pinebark screenings as a growing medium and using overhead sprinklers for irrigation. They are grown in full sun outdoors year round. Each cultivar selected is confidentially evaluated for a period of 5 to 10 years.

The cross resulting in the variety know as ‘WF 712’ was made during 2001. The seed parent is an unnamed, unpatented proprietary seedling, as is the pollen parent. The new variety was selected in the September of 2004 by the inventor in a group of seedlings resulting from the 2001 crossing, at a commercial nursery in Franklinton, La.

Asexual reproduction of the new cultivar was first performed by root divisions at a the same commercial nursery in Franklinton, La. during 2004, and has shown that the unique features of this cultivar are stable and reproduced true to type over multiple generations.


The cultivar ‘WF 712’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘WF 712’. These characteristics in combination distinguish ‘WF 712’ as a new and distinct Hemerocallis cultivar:

    • 1. Excellent landscape performance
    • 2. Orange-Pink flower coloration with rose pink eye zone and lighter pink mid rib and darker pink veining.
    • 3. Early blooming.
    • 4. Repeat blooming
    • 5. 20 inch scape.
    • 6. Dark green foliage
    • 7. Highly resistant to daylily rust.
    • 8. Evergreen foliage.
    • 9. Deep, consistent attractive margin ruffling.
    • 10. Upright foliage

The inventor is unable to compare ‘WF 712’ to the parent varieties, as it is unknown which proprietary varieties are the actual parents.


Plants of the new cultivar ‘WF 712’ are comparable to the unpatented commercial variety Hemerocallis ‘Fairy Tale Pink’. The two Hemerocallis varieties are similar in most horticultural characteristics; however, the new variety ‘WF 712’ differs in the following ways;

    • 1. Much hardier plant capable of withstanding harsh conditions.
    • 2. Rust free.
    • 3. Starts blooming earlier and continues blooming longer with repeated blooming.

Plants of the new cultivar ‘WF 712’ can also be compared to the unpatented commercial variety Hemerocallis ‘Barbara Mitchell’ These varieties are similar in most horticultural characteristics; however ‘WF 712’ differs in the following ways;

    • 1. Not susceptible to daylily rust. The comparator is very susceptible to daylily rust.
    • 2. Starts blooming earlier and continues blooming longer with repeated blooming.


The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘WF 712’ grown outdoors, in a 1 gallon pot. Age of the plant photographed is approximately 1 year old. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
