palaestinum will start about Sept. or later. Do not put this bulb into moist soil before that 
or it will rot. Zantedeschias—pink, yellow and spotted leaf—may be potted by about Dec. 
15. Don’t rush them, as too much water before they start to grow 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. 
_ It is an error to keep large White Callas growing continuously. If rested thru sum- 
mer 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 be- 
tween 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. Large, 
50c. 3 
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, but 
always beautiful. 50c each. 
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. 
Arum palaestinum. Black Calla. Solomon’s Lily. Foliage and flowers are shaped like 
callas but flowers are black. 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. | 
Anthurium. Until very recently these have been high in price. We have had con- 
stant inquiries for them and now that prices are really reasonable we are pleased to list 
them. The cordate leaves make them useful as foliage plants alone but a mature plant 
will flower six times a year. Flowers are calla-like in red, pink and sometimes white. 
They are much used as florists flowers. Flowers last six weeks on a plant. 
Anthurium andraeanum. Shaffer Hybrids. These are considered to be the best An- 
thuriums. Fls. up to 6” long, orange-red, varying to rose or white. 6” to 8” plants that 
should begin to flower at 10” to 12”. Sometimes they flower even at 8”. Assorted colors, 
$3.75. Red, $5.00. Shaffer's Best Red, $6.00. Blooming size, about 12”, assorted colors, 
$6.00. Large plants in bloom, $7.50. 
A. scherzerianum. This species does not make as large plants or flowers as andrae- 
“anum, but they are interesting and pretty. Their advantage is their greater hardiness. 
They are easier for amateurs and as house plants. They are not quite so demanding about 
temperature and humidity. They flower from very small sizes. Blooming size, $3.75. We 
have a few of the var. Atrorubrum, dark red, for $6.00. 
A. crystallinum. A beautiful foliage plant that does not need flowers, tho it has green 
fls. Leaves are cordate-ovate to 10” wide and 14” long, deep velvety green, prominently 
veined white. Pale rose on under side. $5.00. . 
Spathiphyllum clevelandi. Close relative of Anthurium and formerly so classified. 
Fls. are white and freely produced. Very easy to grow. Blooming size, $3.75. . 
Culture of Anthuriums and Spathiphyllums. These are tender tropical plants, suitable 
only for pot culture. Soil formula: We prefer to use about 14 old osmundine; 34 peat. 
Add enough sponge rock or coarse sand to hasten rapid drainage and aerate the compost. — 
One can also add a little oak leaf mould. They will grow in any compost with sand. Add 
a thin layer of spagnum 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. | 
A rounded tablespoonful of powdered dairy manure to a 5” pot is recommended. _-
