A commercial nursery is : not. conducted by this department, but we do 
propagate and distribute new varieties originated in this department or imported 
from similar climates of the World. Improvement in size and quality of the 
Horticultural meterial has been observed each year since 1895 in the many acres 
of seedling fruits. Hybridization and selection are the main methods of improve- 
ment. The work has been honored by extensive propagation and planting of many 
of the new varieties and by four medals awarded to Dr. N. E. Hansen. The George 
Robert White gold medal of honor for "eminent service in horticulture" by the 
Massachusetts Horticultural Society, 1917; the Marshall P. Wilder silver medal 
by the American Pomological Society for new fruits, 1929; gold medal for public 
service by Cosmopolitan club, Sioux Falls, 19333 A. P. Stevenson gold medal for 
new fruits by the Manitoba Horticultural Society, 1935, were given for out- 
standing service to the field of Horticulture. 
Many new seedling fruits, roses, other ornamentals and vegetables are 
coming on, which will be released as soon as they are up to standard. Some of 
the material in this list is offered primarily for distribution to plant-breeders 
to help in the work of improving hardy fruits and roses elsewhere. 
Terms: Terms are cash with order. For South Dakota orders add three per 
cent to the above prices for State Retail Sales Tax. The money received from the 
sole of plants makes it possible to do the work on a larger scale than would 
otherwise be possible. It is important to order promptly, as soon as this list 
is received, as the supply of plants is limited. 
Note: There are no propagation restrictions on any of these new varieties. 
Hidatsa: A Hardy Double-Flowered Hawthorn 
Offered for the first time. 
In England, Hawthorn hedges are one of the greatest charms of the rural 
landscape. This species, Crataegus oxyacantha, is native of Europe and north 
Africa and is not hardy enough for the prairie Northwest. There are a number of 
varieties in England of which the best is Paul's Double Scarlet Hawthorn. Several 
years ago, Dr. N. E. Hansen crossed this variety with the native wild Hawthorn of 
Pilot Mound, Manitoba. A number of seedlings were obtained that are very orne- 
mental. Hidatsa, the first to be offered, has abundant double flowers that are 
light shell pink in color. The glossy, attractive foliage with cach sprig pro- 
vides a "beautiful, ready-made corsage." (Hidatsa: a Sioux Indian tribe). 
There are at least seven of these beautiful hardy double Hawthorns. Their 
relative merits must be determined by further trial elsewhere in South Dakota and 
other stetes. Hidatsa Hawthorns will be widely popular as small ornamental 
lawn trees. W. J. Bean, a noted English author, said none make lovelier lawn 
trees than the Hawthorn. 
Hawthorn seedlings or pear may be used as understocks; Hidatsa Hawthorn, 
scions only, per foot, $1. 
Siberian Apricot 
The Siberian Apricot, a distinctly different variety from the Manchu Apricots 
released from this station in 1937, is an interesting ornamental shrub or small 
tree, around ten feet high and ten feet across; flowers appear early, white to 
light pink; leaves round ovate, long-poirited; fruit inedible, the flesh splitting 
into two leathery parts. Linnaeus named it Prunus Sibirica; later authors classify 
it as.a subspecies of the common apricot, Prunus A Armeniaca, Linn. var. Sibirica, 
Kochi The greatest value of this species may be as a nursery understock for the 
Mancht-apricots. In budding in nursery they unite in an apparently perfect union. 
It should cause earlier bearing as it is more dwarf in growth than the tall- 
growing Manchu apricots. In addition it has much ornamental value as the small 
trees are loaded with blossoms.
