DUTCH IRIS 
We have been amazed at the enormous numbers of Dutch Iris 
that our customers have purchased the last few years. Apparently 
a good many gardeners are only now learning of their great beauty 
and ease of culture. We think the great popularity of these choice 
bulbs is well justified. Because of their beautiful harmonious colors 
and long lasting qualities they are unexecelled among the bulb 
flowers for either the garden or for cut flowers. By proper choice of 
varieties one can spread the blooming period over two months or 
more. The season starts with Wedgewood during the Darwin Tulip 
’ season and ends with the English Iris in June. 
A. BLOEMAARD. One of the earliest of the Dutch irises. Large 
flower with dark purplish blue standards, deep blue falls with narrow 
orange stripe. 12 for 80c, 100 for $6.00. 
BLUE HORIZON (S. de Vlieger). Very beautiful light blue iris of 
large size. Good stem and foliage. The very broad and strong falls 
are soft sky blue. 12 for 80c, 100 for $6.00. 
D. HARING (White Glory). A splendid tall vigorous white iris. 
One of the finest and most dependable varieties in the list. The 
large flowers are pure white except for the narrow yellow mark on 
falls and a faint tinge of lavender in the standards when it first opens. 12 for 
$1.00, 100 for $7.50. 
GERRIT VAN HEES. A beautiful new variety having large falls of rich 
royal blue marked with a pale yellow stripe. Broad purplish blue standards. 
12 for $1.00, 100 for $7.50. 
HUCHTENBURG. A tall growing iris of large size and attractive coloring. 
The falls are deep yellow and the uprights are very pale blue passing to white. 
12 for $1.00, 100 for $7.50. 
IMPERATOR (Filifolia). Later blooming than the true Dutch irises, con- 
necting them with the Spanish. Deep blue standards and falls. Large, free 
flowering and a vigorous grower. 12 for 80c, 100 for $6.00. 
INDIAN CHIEF (W. Verschuur). An interesting and attractive novelty 
providing an unusual shade in the Dutch Irises. The falls are yellowish bronze, 
standards light violet shaded bronze. 12 for $1.25. 
fF MORNING MIST (Jan Weenix). A beautiful delicately colored iris. Large 
flowers with both standards and falls of soft lavender-blue. Height 30 inches. 
12 for $1.00, 100 for $7.50. 
JACOB DE WIT. A splendid medium blue iris—darker than Blue Horizon 
and lighter than Imperator. The falls are large and somewhat waved, stand- 
ards dark blue. 12 for 80c, 100 for $6.00. 
THERESE VAN DUYLL SCHWARTZE. A tall and graceful iris that makes 
an especially attractive cut flower. The standards are pale cornflower blue, 
falls pure white with narrow orange stripe. 12 for $1.00, 100 for $7.50. 
VIOLET QUEEN (W. Zuiderveld). The coloring of this iris is quite unique 
and difficult to describe—perhaps light violet-lilac gives some idea of the 
unusual shade. A large strong growing variety—the finest in its color. 12 for 
$1.00, 100 for $7.50. 
WEDGEWOOD (Tingitana Hybrid). This variety has very large flowers 
that appear fully two weeks before the regular Dutch iris. The falls are clear 
Wedgewood blue and are stronger and larger than the other varieties. Our 
strain is exceptionally good. 12 for $1.00, 100 for $7.50. 
WHITH EXCELSIOR. Large pure white flowers of very good form and 
substance. Medium height. Early. 12 for $1.00, 100 for $7.50.

In this short space we cannot give complete cultural instruc- 
tions for all the different kinds of bulbs, but there are a few 
basic facts, which if understood, will enable any one to have 
success—most of the time. We will be glad to send a booklet 
on growing bulbs if you ask for it with your order.

SOIL. Nothing fancy is needed, just good garden soil reason- 
ably well supplied with plant food. We always add Vigoro or 
similar fertilizer before spading up the ground, which should 
be prepared deeply, 15 inches or more. Organic manures in 
moderation are good if applied at least a year in advance. 
MOISTURE. The bulbs should have ample moisture from 
the time they are planted until they ripen off. Water should 
eles stand over the bulbs—this is especially important with 
ulips. 
CUTTING FLOWERS. Naturally you want to cut many of 
the blossoms. That is one of the main reasons for growing 
the bulbs. It does little harm to the bulb if you go easy on 
the foliage. The plant needs its green leaves to feed the bulb 
for next year. Remember! The bulbs make almost all of their 
new bulb growth between the time of flowering and the ripen- 
ing of the foliage. Keep them growing as long as you can. 
SEED FORMATION, Always remove the wilted flowers or 
seed pods. If the bulb is allowed to form seed, it doesn’t work 
so hard at growing bulbs for next year. This is especially true 
with tulips. ; 
DIGGING TIME. Dig bulbs when the foliage is turning 
yellow and becoming lifeless. Do not wait until it is dry and 
dead. Never expose the bulbs to bright sunshine but take 
them immediately to a cool place out of the sun and wind.
