New or Noteworthy Plants 
Including Colorado Wild Flowers of Mountain and Plain, and other Perennials for the 
Border and Rock Garden. 
Under this section will be found a wealth of choice plants for the average American 
garden; the best of old and new offerings, and many exclusive items not obtainable else¬ 
where. 
With a few exceptions, to be indicated, 
all are of easy culture. They are hardy and 
adaptable throughout the trans-continental 
area from the Pacific Northwest to New 
England. The line of equal hardiness bows 
to the southward as one advances inland 
from either coast-line. Our latitude and 
mile-high altitude assures utmost hardiness 
and stock that is full of pep and vitality. 
The inland northern border of the U. S. has 
growing problems that are best understood 
locally. I do not attempt to advise, but sug¬ 
gest that among our native mountain flow¬ 
ers and shrubs are extremely valuable 
things for the coldest climates. Their con¬ 
tribution to any particular locality in the 
extreme north must be determined largely 
by experiment. 
A rather wide area to the north and south 
of parallel 40, the latitude of Boulder, may 
accept with confidence any of the material 
here offered. Be reminded again of flowers 
new to most gardens, able to add zest and 
interest to your garden endeavors. Make 
it your slogan each season, to “Plant some¬ 
thing new.”

Culture of Alpines. The word alpine is 
often used in the general sense, including 
any mountain plant. True alpines from the 
alpine zone at timberline and above, require 
special care in growing, and will not suc¬ 
ceed ordinarily in a mixed planting among 
rank-growing species of the border and rock 
garden. Alpines and certain sub-alpines of 
brookside and mountain bogs require much 
more moisture and coolness, usually with 
partial shade. 
The moraine, here considered merely as a 
subirrigated bed, is the practical answer, 
and need not be too costly, provided one has 
an unfailing water supply as a spring or 
city connection. The basin for the moraine 
may be a converted pool, but a little drain¬ 
age must be provided, else it will become 
stagnant. In a fairly retentive soil cement 
ing will be unnecessary. It may be walled 
to the surface and rocks may be placed to 
simulate a rock garden. When filling, place 
four to six inches of broken stone and (or) 
coarse gravel over the bottom, inserting a 
tile or short pipe through which to apply 
water, so that the upper end will reach just 
above the ground level. Then cover with 
inverted sods and fill with suitable compost, 
preferably a mixture of stone chips, sand 
and humus; no rich fertilizer is permissible. 
A little experience will determine how much 
and how often water should be given; a lib¬ 
eral filling once or twice a week should be 
sufficient, even during dry weather. Dur¬ 
ing winter, watering should be discontin¬ 
ued, and a mulch should retain sufficient 
moisture till spring growth begins. 
The soil for Colorado plants in general 
should be of mellow texture, well supplied 
with humus, not very rich. The natural 
habitat for nearly all mountain flowers va¬ 
ries from nearly neutral to acid; an exces¬ 
sive lime content should be avoided. 
Distance is no barrier. Perfected packing 
and dependable Postal and Express deliv¬ 
ery practically puts my nursery at your 
door.
