In the introduction year, A.B. Stout described it as:
" The Soudan Daylily somewhat resembles the old popular Lemon Daylily (Hemerocallis flava), but it blooms in New York in July after the former is entirely through flowering. In comparison with the Lemon Daylily the plant is somewhat larger, the scapes are taller, and the flowers have broader petals and this makes a fuller flower, but in general color and size the flowers are nearly the same. Hence those who are fond of the Lemon Daylily will find the Soudan Daylily of interest and value in continuing this class of plant and flower into the midsummer season.
The foliage of the Soudan Daylily is medium coarse, medium dark-green, and ascending to a general level of about two feet. The scapes are about three feet tall, branching, nearly erect, and holding the flowers well above the leaves. The flowers are clear empire-yellow in color and gold-glistening; the petals have somewhat wavy margins, and they are wide and overlapping, making an unusually full flower with a spread of about four and one half inches. The plant is day-blooming, very floriferous, and an excellent summer-flowering sort.
In obtaining the seedling that is being propagated under the name Soudan Daylily, the Hemerocallis flava (Lemon Daylily) was hybridized with H. aurantiaca and a selection in this progeny was then crossed with the Luteola Daylily, which is itself supposed to be a hybrid between H. Thunbergii and either H. aurantiaca or H. aurantiaca major. The progeny of this diverse parentage had flowers of various shades of yellow and orange coloring, with, in a few cases, tinges of fulvous. Two of this particular series of hybrids have already been named the Vesta Daylily and the Wau-Bun Daylily. "
