DELPHINIUM SPECIES 
HYBRIDS 
“WEST O’ THE ROCKIES” STRAIN 
Comments: 
About 15 years ago, we assembled a collection of Delphinium 
species, mostly natives of the Western United States. The object 
of growing these various types was to determine their adapta- 
bility to garden culture; to note their susceptability to natural in- 
tercrossing; and particularly to use in controlled combinations for 
red development. 
As a basis for the hybridization program, the D. species and 
varieties: NUDICAULE, CARDINALE, MENZIESH, OCHRALEU- 
CUM, NELSONI, TROLLIFOLIUM, PARRISHII and others were 
used as parent plants. From six to fourteen years of work has 
been expended on the development of these various Hybrids. 
After much garden testing, they are now deemed worthy of re- 
lease to the gardening public, and will be distributed, as rapidly 
as increase of stocks permit. 
Each of these Series have been the subject of comment in 
past issues of the American Delphinium Society Yearbook, as 
well as in other publications. 
Like all other Delphinium, these species derivatives are not 
perfect in every detail, but like other Delphinium have many 
fine qualities and potentialities. They are new and “all American” 
in origination; are developed soiely from North American species 
and varieties. They have the fine qualities of being floriferous, 
vividly and harmoniously colorful and excellent for cutting and 
arrangement. They are easily grown from seed, and are adapted 
to various garden positions, and are winter hardy in many 
localities. 
It is hoped that these series will be carefully tried by all 
DELFANS. In these Hybrids are the elements of many new 
characters of color, type and adaptability, hitherto unknown in 
Delphinium stocks. As foundation material, upon which to build 
new Delphinium beauty, they should be of immense value. We 
feel privileged to have had the opportunity to supply, in these 
D. species Hybrids, some of these new characters, and to share 
them with other plant folks. 
Our Delphinium Garden, like any hobbyist’s workshop, is 
not always a showplace. In season it is a busy place, wherein 
the development and improvement of Delphinium species Hy- 
brids is the foremost project. We look forward to continued 
work in this project; the products of which we hope will even- 
tually grace the borders and gardens of many present and fu- 
ture homes.
