ARACEAE. (ARUMS, CARLAS, ETC.) 
This family contains the so-called Calla Lilies or Zantedeschias, Fancy 
Leaf Caladiums and other Aroids offered in our fall catalog. 
Culture. Callas for house culture should be potted at once. Use a 5" of 6" 
pot and cover bulbs about 1". Use soil containing plenty of peat or leaf mold 
as they need an acid soil. Place pot in deep shade until they start then give 
them a sunny window. They bloom early. After blooming and as soon as the 
weather is warm, all frost danger past, they may be shifted to the garden. Or 
they may be planted very early in the garden. In California plant at once and 
up to about April 1. Give full sun along coast, light shade in mid-day is good 
in hot, sunny climates. The liberal use of peat advised. They are semi- aquatic 
and need to be constantly wet to succeed. Dig and store colored callas in the 
south as well as north tho they usually live over winter in the ground here. 
■White Callas will grow continuously if kept wet, but that way they seldom 
bloom. When they quit blooming let them grow a while then withhold water 
entirely. Give them a good rest, completely dry, but do not remove from the 
soil. 
Zantedeschia aethiopica, var. Baby Calla. This is the smallest and whitest 
Calla. Small enough for corsage. L. 35c; small 25c. 
Z. aethiopica, var. Godfrey Calla. The best and most popular of dwarf 
Callas before “Baby” was introduced. Being twice as large as Baby makes it a 
“medium” size. This is so much more appropriate in size, freer in blooming and 
more desirable every way that we do not recommend the large type. 20c and 30c. 
Z. Albo-maculata. The prettiest foliage of all and worth growing for that 
alone. Special. Small bulbs that may not bloom first year but I think they will 
with good culture—10c. Large 15c and 20c. 
Z. eUiotiana. Pure golden yellow flowers. 15c to 25c, all blooming size. 
Z. rehmanni. The famous pink Calla. Colors vary from pink to rose red. 
The plant and flowers are small, growing only to about 12". 50c, 75c and extra 
large for $1.00 The larger sizes bloom more surely for amateurs. 
Amorphophallus rivieri. Large plant up to 4 ft., very decorative and trop¬ 
ical in appearance. Flower often 3 ft. long, rich chocolate dotted with red. 
Carrion odor. Bulbs do not bloom until very large. In the south plant outside 
in semi-shade, 3" to 5" deep. In the north they are grown in large pots. Only 
very large bulbs bloom and these not guaranteed for first year. S. $1. each. 
Sizes at $2., $3. to L. $4. 
Arum palaestinum. Black Calla or Solomon’s Lily. This must not be 
planted earlier than August 1 and preferably not before September 15. Bulbs 
ready for delivery in June. Plant and flowers look like Callas but flower is 
really black. Flower has no bad odor. Successful in pots in north and quite 
hardy outside in south and middle south. They prefer part shade. S. 25c. 
Small blooming size, 35c. L. 75c. Jumbo $1.00. Give the Jumbo size a 10" pot. 
Fancy Leaved Caladiums. Assorted colors. The flowers are inconspicuous 
but the leaves are as richly colored and gorgeous as a whole bouquet of flowers. 
Our bed of these last summer attracted unusual attention. It was a gorgeous 
riot of color. 
Culture. Our first attempt at growing these 25 years ago failed and we 
considered them unsuited to our hot dry climate. But we now grow them to 
perfection, and understanding them, it is very easy. Every sub-tropical garden 
can have them. We will tell you how. 
The soil should be very rich sandy loam with a very large amount of old 
rotted manure thoroughly mixed-not lumpy. Then add some leaf mold and 
perhaps peat. This last because they like an acid soil. Leaf mold from beneath 
oak trees is the most acid. Bone meal is recommended but is not essential. 
They are such gross feeders that we have laid forkfuls of nearly fresh dairy 
manure around them but not touching. Manure should be added as a mulch
