may rot them. They may be held back and started in early spring, here in late February. 
All do well in the garden in a moist semi-shaded cool place. They are not hardy in cold 
climates; dig in fall. The White Calla usually blooms in California in the garden in late 
winter. They may be planted in early fall in pots or garden. All do best in mildly acid 
soils, on sandy side. For acidity add peat. Most Aroids are shade plants. 
It is an error to keep large White Callas growing continuously. If rested thru 
summer you will be rewarded with flowers. Callas as pot plants need some sun, enough 
to prevent spindly growth, plenty of light and like all plants, good ventilation. They 
need abundant water but good drainage. 
Zantedeschia aethiopica. Well known White Calla. They can be potted anytime 
between Sept. 1 and Jan. 1. Even later if available. Water once when potted to settle soil. 
Then keep soil barely moist until growth is well started. When growing well they need 
plenty of water and perfect drainage, give about half shade. They are hardy outdoors 
down to 15° but tops may be cut down by frost at about 20°. Blooming size, 25c. 
Larges 50c. 
Z. albo-maculata, Spotted leaf calla. White flowers and ornamental foliage. As for 
the other callas they need enough sun to prevent spindly growth. We have small to 
very large. 40c, 60c and 75c ea. 
Z. rehmanni elegans. Light pink Calla. Easier to grow and flower than the dark 
pink. A few are very light, almost white when forced but darker in the garden, and 
always beautiful. Large bulbs, 40c. 3 for $1.15. Delivery Nov. 
Z. elliotiana. Deep Golden Yellow Calla. Like all the callas, they need some sun. 
If they do not have it they grow too tall and weak and may fail to flower. Half sun is 
usually right. 30c ea. 3 for 85c. Delivery Nov. 
Arum palaestinum. Black Calla. Solomon’s Lily. Foliage and flowers are shaped 
like Callas but flowers are black and odorless. Plant 4” deep in garden, not so deep 
in a pot. Begin to water about Sept. 1. Flowers in Feb. Large for 75c and $1.00 ea. 
Small; foria\ start, 4356 
Anthurium andraeanum. Until very recently these have been high in price. But 
now prices are really reasonable. The cordate leaves make them useful as foliage plants 
alone but a mature plant will flower six times a year. Flowers are calla-like, but rather 
flat, in glossy red, pink, orange, coral, rose and rarely white. They are much used for 
cut flowers in arrangements and corsages. They are ever-blooming if given correct 
conditions at all times, but sometimes take a vacation when very hot, very cold or 
very dry. 
Culture. Anthuriums and Spathiphyllums are tender tropical plants, suitable only 
for pot culture. Soil formula. They will grow in most any organic compost. We use 
and advise one part old osmundine, (discarded from orchid pots, new will do); one 
part peat. Add enough Sponge Rok or coarse sand to make compost very gritty and 
to hasten quick drainage. See Potting Directions under General Culture. Add a thin 
layer of sphagnum on surface to prevent eroding the surface when watering. Set plant 
low in an oversized pot and as it grows, new roots are formed on compost surface 
which should be covered with more sphagnum. When compost surface reaches rim 
of pot, shift to larger pot, or build up with sphagnum. New roots must be kept covered. 
Use Spoonit or liquid manure once a month, after plants are well established. The 
preferred minimum night temp. is 60° or over. 45° does little harm other than to 
stop growth and flowering. 70° to 80° is a good daytime temp. Air should be very 
humid. Spraying foliage daily increases air humidity. They should never become 
completely dry, thruout. Water about every two days. 
Shipping. The best way is in pots, by express. But you pay the express and it costs 
us more to pack. Plants are set back a little by sending by mail, out of pot. But they 
recover and you save quite a lot on the total cost. Which compensates for the recovery 
period. If by mail you should add 35c for plants under 8” and 45c for larger sizes for 
“Special Delivery,’ also for Insurance fee if desired. They cannot be mailed in cold 
weather. 
Anthurium andraeanum, Shaffer Hybrids are the best. Plants should begin to
