BIOGRAPHICAL NOTE
Arlow
Burdette Stout (1876-1957) stands as a seminal figure in the advancement
of the science and hybridization of daylilies. Dr. Stout was born in Albion,
Wisconsin on March 10, 1876. Early in his career Dr. Stout was a teacher
in rural schools. He graduated from Whitewater (Wisconsin) State Normal
School in 1908 and went on to gain his B.A. degree at the University of
Wisconsin, where he later taught botany. Afterwards, in 1911, The New York
Botanical Garden appointed him Director of Laboratories, launching a 36-year
career as a geneticist, plant-breeder, and educator. His appointment was
concomitant with matriculation into graduate studies at Columbia University,
under Professor R. A. Harper, where he gained his Ph.D. in 1913. During
his career at the Garden he made his home in Pleasantville, New York.
Dr. Stout himself best defined the essence of his life's work as a research
scientist. In a summary of his life written in 1956, the year before his
death, he stated, "His main technical research was concerned with experimental
studies on the nature and genetics of intraspecific self- and cross-incompatibilities
in the sexual reproduction of flowering plants." An accurate statement,
but one which does little justice to the evolution and details of his accomplishments.
In his 1939 autobiography he enlarged the description of his investigation
of the "processes of seed reproduction in flowering plants." In 1919 Dr.
Stout initiated an experimental study to produce seedlessness in grapes.
This continued as a lifelong project that resulted in the introduction
of scores of new kinds of grapes. Later, after an investigation into the
flower behavior of avocado, his contributions to the improvement of its
commercial production were dramatic and newsworthy; the New York Times
(March 6, 1927) reported, "Finds Flower's Sex Changes Each Day." The title
referred to Dr. Stout's "astonishing" discovery that the avocado flower
reverses its sex from male to female and vice versa on a daily basis, consequently
producing fruit irregularly. His findings led to the breeding of male and
female flowers in close proximity that resulted in productive, instead
of barren, orchards. Though often he seemed completely focused only on
garden work and experimentation (and he considered himself a gardener in
a direct sense), the impact of Dr. Stout's work continued to be widely
publicized.
The focus on the self-sterility of Lilium (lily) and Hemerocallis
(daylily) was the backbone of success in selective breeding and led to
the development of stunning hybrid flowers that brought great horticultural
value. Self-sterility in flowers refers to the incapability of the ova
of flowers in certain species to become fertilized by the individual flower's
own pollen. It has been noted in many places that Stout observed this phenomenon
in his mother's garden as a boy. What resulted was the regular failure
of the familiar tiger lily and the fulvous daylily to produce capsules
and seed. He began investigating this reproductive anomaly in his first
year at The New York Botanical Garden and continued systematic selective
breeding for more than three decades. In over 50,000 cross-pollination
experiments, Dr. Stout produced over one hundred viable Hemerocallis
hybrids, revolutionizing nursery breeding and popular interest in daylilies.
Without a doubt, Dr. Stout's public renown rested largely on the knowledge
and innovation he brought to the breeding of daylilies. His success led
Dr. Henry A. Gleason, Head Curator of the Garden in 1938 to remark, "It
is not unlikely that the commercial value of the work of Dr. A. B. Stout
. . . will exceed the entire cost of the Garden during the forty years
of its history."
From his position as Curator of Education and Laboratories at the Garden,
Stout lectured widely, even in radio program broadcasts, on his findings
in the breeding of daylilies. His publications numbered over 350, including
the landmark monograph Daylilies, published in 1934 (reprinted in
1986), and Reproduction in Petunia (1952). He established business
relationships with local nurseries, notably the Bertrand Farr Nursery Company,
in programs to evaluate and propagate his hybrid clones. He coordinated
several lines of research and their practical application. This included
a long-term project for the selection of hardy poplar trees in association
with the New York Agricultural Experiment Station in Geneva, New York.
Of his many scientific affiliations, Dr. Stout was an Honorary Life
Member of the Horticultural Society of New York and an Honorary Life Fellow
in the Royal Horticultural Society. He was a fellow of the American Association
for the Advancement of Science, the American Society of Naturalists, and
of the Botanical Society of America. In 1937 he received the Thomas Roland
Medal of the Massachusetts Horticultural Society and won a gold medal for
an exhibit of seedling daylilies by the Horticultural Society of New York.
The American Hemerocallis Society established in 1950 a Stout Award
in his honor, considered the most distinctive award in annual recognition
of a Hemerocallis clone. In 1954, seven years after his retirement,
The New York Botanical Garden honored Dr. Stout with a Distinguished Service
Award for "outstanding contributions to the advancement of horticulture
and botany."
At the end of a fulfilling career of tireless labor and dedication,
as well as life accomplishments recognized in arenas both scientific and
public, Dr. Stout enjoyed ten years, amidst the setbacks of illness, of
his post-retirement life. He died at the age of 81 on October 12, 1957,
at his home in Pleasantville. In a letter of November 1953 he wrote of
some infirmities and of his hopes to complete a work on the evaluation
of the botany of Hemerocallis. Yet he admitted to his correspondent
that "if I do not get to any more reports on Daylilies we can say;
---
With daylilies
We have done
What
We leave done
Now
We are done
With daylilies"

reprints, and awards. It covers Dr. Stout's entire career at The New York
Botanical Garden (1911-47). There is a small selection of papers from his
high school years (1899-1903) and graduate study at Columbia College (1911-13).

sequences. The first sequence is arranged alphabetically by species; the
second is arranged chronologically by year; and the third, 'inflorescence,'
is arranged by species. There are also notebooks and files on Hemerocallis
hybrids and clones. The sequence of photos (the fourth photo sequence)
which follows is arranged alphabetically by hybrid name. See Appendix I

is organized in two sequences, glass or acetate. Negatives are numbered
by year and/or hybridization number and are cross-referenced with corresponding
positives of Series 2, above. Most material documents species and hybrid
studies (indoor and outdoor), life cycle studies, staged displays, garden
views, landscapes, and plant structure studies, e.g., seeds, capsules,
foliage, scapes, and flowers. There are photomicrographs of plant cell
structure, comparative studies of Hemerocallis clones, herbarium
specimens of the Kew Botanic Garden, imported packages of dried daylilies
for use as a food vegetable, and portraits of Dr. Stout at work, including
views of the New York Botanical Garden experimental garden.
