IRIS FAMILY—Iridaceae 
The Iris is the type genus of this family, which includes Iris, Gladiolus, Watsonias, 
Freesias, Sparaxis, Tritonias, Babianas, etc., listed on the following pages. ; 
Tall Bearded Iris. These will be listed in our spring catalog which you will receive 
in Jan. We advise June or July planting up to early fall. But many growers advise fall 
planting. If planted in late fall one gets fewer flowers the following spring than if 
planted earlier. But we planted in mid-winter last year and much to our surprise we had 
a lot of flowers. It all depends on the amount of growth one can get on the plants and 
Iris grow all winter in So. Calif. It is always better to plant in the fall than to wait until 
the following year. 
If you are interested in planting Iris this fall or winter send us 10c for our 
Spring Catalog. The 10c is necessary because we have only a few hundred and must 
limit distribution to those who want to buy. Also ask for our special price list of the 
higher priced newer introductions, entitled “The Iris Four Hundred.” Please do not 
send for either list if you do not intend to buy. : 
Dutch Iris. These are bulbous Iris. The flowers are not fragile like bearded Iris 
and they are therefore very useful for cutting. 
Culture. They should be planted in the fall before Oct. 30 as the bulbs often 
deteriorate after that date. Later plantings may succeed if bulbs are good and not infested 
with plant lice. Plant 1” to 3” apart and 3” to 4” deep depending on size of bulbs. They 
are hardy in milder sections of north but a mulch is advisable. Full sun or slight shade. 
Blue Horizon. Very beautiful flower, broad and sturdy. Light violet blue standards 
and soft sky blue falls. 27” tall. 3 for 25c 85c doz. 
Imperator. Tall, dark blue. Favorite for cutting. 3 for 20c. Per doz. 70c. 
Jacob de Wit. A very early dark blue. 3 for 25c. 85c doz. 
Wedgewood. A most lovely Wedgewood blue. The earliest to flower. Popular 
florists flower. In the north it needs protection of a winter mulch. It will force in pots. 
3 for 25c. 85c per doz. 
Yellow Queen. Pure deep golden yellow. 3 for 20c. 75c doz. 
Assorted varieties. The above and other sorts. 3 for 25c. 85c per doz. 
Iris Spuria should be planted in the fall in full sun or part shade. Set the rhizome 
shallow as for bearded Iris and keep moist until they are established. Altho they do well 
under average garden conditions they do best with abundant moisture. 
I. spuria aurea. Deep yellow. 50c. 3 
: I. spuria ochroleuca. 4 ft. White with yellow blotch on falls. Excellent cut flower.

Gladiolus 
How to Grow Gladiolus. Glads planted Nov. 15 to Mar. 1 in Southern California 
and thruout the south (a little later in Northern California and early as possible in spring 
in the east) are reasonably sure to escape the attack of thrips. Our Glad bulbs are especially 
grown for this purpose, matured early and dug in August. But if you plant recently dug 
bulbs you will gain nothing; they will continue their rest of three months before starting. 
Thrips are very small insects that suck the juices from the plant. They cause the 
flowers to wither or appear burned, and appear only after weather becomes warm. To 
avoid the damage thrips do, four measures are effective. Plant early. Plant clean, treated 
bulbs. Keep them reasonably moist and well cultivated, with no weeds. 
The total elimination of thrips appears impossible. A few are bound to appear as 
the weather becomes warm. 
We therefore begin to dust with D.D.T. when plants are about 8” tall. Any hand 
duster will do. We use a powder containing 5% D.D.T., 45% Sulphur and 50% inert 
ingredients. Dust in early morning when the plants are moist with dew. That will cause 
the powder to stick and remain effective for a week or two. Four to six dustings before
