warm winecup crimson of Callirhoe, strayed over from a 
planting nearby. The buds remind one of roses about to 
open. Pkt. 10c; % oz. 30c; % oz. 50c, (Plants, each 15c; 
3 for 40c; 9 for $1.00.)

a splendid strain of this freest in blooming of all Cactus 
groups. Magnificent flowers in cream, pink, orange, scarlet, 
crimson, lavender and purple. Oddly compressed, flanged 
and margined plant stems. Due to war, we may perhaps, 
not receive our usual stock from the European Phyllo- 
cactus specialist who has supplied us for so many years. 
We ask our friends to let us have their orders as usual, 
for we hope to be able to fill them as usual. If we find 
that we cai.not do so, all payments will be refunded, 8 
seeds for 25c; 18 seeds for 50c; 40 seeds for $1.00, 
OFFER 33A40—One pkt. each of above for $3.25. 
CACTUS HARDY BLEND—kt. Many Cactus species are 
thoroughly winter-hardy, even into Canada. Others are so 
nearly hardy that they may be easily wintered out of doora 
in the North with but slight protection. Here is a splendid 
mixture. 20 seeds for 15c; 50 seeds for 35c; 100 for 65c; 
500 for $2.75; 1000 for $5.00. 
CACTUS ORNAMENTAL BLEND—w. For pot culture, 
being mostly not hardy outside. Weird and curious stem 
formations, with richly hued and feathery flowers, followed 
by “jewel” fruits. Wonderfully diverse blend, including 
seeds of a vast number of decorative species not described 
separately here, 20 seeds for 15c; 50 seeds for 35c; 100 
for 65c; 500 for $2.75; 1000 for $6.00. 
21 CALANDRINIA UMBELLATA—erdx(2-4)6. Clustered

effect. Clewing color for months; being perennial, re¬ 
peated summer after summer. Sun-loving and drought- 
enduring. Pkt. 15c. (Plants, each 30c; 3 for 85c.) 
CALCEOLARIA 
Variations on a pleasing theme 
22 CALCEOLARIA BIFLORA—erx(2)6. A rare perennial 
of the Andes, reasonably winter-hardy in the rock garden. 
The flowers are pretty little lady-slippers of golden yellow, 
always in twins (as indeed slippers should be.) Rosettes of 
prostrate leaves. Pkt. 26c. 
25 CALCEOLARIA PEERLESS HYBRIDS—w. A splendid 
pot plant, or may be plunged outside in summer. Giant 
slipper or purse-shaped flowers in a continuity and freedom 
of blooming almost beyond belief. Colors vary from lemon, 
through gold and brown, to copper and crimson, often 
splashed or tigred contrastingly. There is, we believe no 
larger-flowered, or more variably and brilliantly colored. 
Calceolaria strain than this. Pkt. 25c. 
-CALENDULA AVALON SPECIAL 
The Scottish Marigolds, or Calendulas, are excellent dec¬ 
orative subjects for the summer garden, but perhaps they 
are most valued for cutting. In continuous bloom from 
early July until frost. Of easiest possible handling. Won¬ 
derfully variable in both color and form, cream, lemon, 
apricot, chrome yellow, golden, tangerine and orange that 
may sometimes show hint of scarlet; blossoms quilled, 
whorled. rayed like a Cactus Dahlia, or sometimes shaggy 
as a Chrysanthemum. Our Avalon Special is made up 
altogether from segregated strains, and the better named 
varieties. We blend it ourselves, and we_ include no 
“grown-in-mixture” stock. The Avalon Special is worth 
more than we ask for it, Pkt. 10c; % oz. 20c; 1 oz. 70c. 
THE CALLA LILIES (Zantedesehias) 
They make splendid winter-blooming pot plants, or they 
can be handled to flower in the garden in summer, where 
they will give most unusual, and attractive, decorative 
effects. All this applies to the kinds listed here, but with 
two exceptions that should be noted. The Black Calla will 
please best if handled only for winter pot-flowering, and 
the Spotted Calla when grown only for summer garden 
flowering, where, incidentally, it has its greatest effective¬ 
ness as a pool-edge or stream margin plant. About that 
choice of summer or winter flowering with the others; 
you will have to make up your mind as to which. Don’t 
try both seasons in succession with the same tubers. During 
the “off” season, let the dormant or semi-dormant roots 
rest in a cool cellar. All Callas grow quite quickly and 
easily from seed. Illvstiated, page 59. 
CALLA, THE BLACK AND YELLOW—€mx(w)20. Rare. 
Straw yellow, velvet black at base. Z. melanoleuca. 4 seeds, 
25c. (Tubers, each $1.00.)

low. Seed-crop failed, but good tubers are available, bloom¬ 
ing size, at 25c each, 3 for 70c. It is Z. Elliottiana. 
CALLA, THE BLACK—k.20. Big flower-spathes, dull black- 
green without, but inside a rich and velvety midnight 
maroon. It is Arum palaestinum. Tubers only, ready Sep¬ 
tember to December, each 40c; 2 for 75c. 
CALLA, THE PINK—ex(w)12. Alluring colorings, palest 
blush, through pure pink, to rich rose. A very occasional 
tuber will be white-flowered. Dwarf, compact, floriferous, 
6 seeds for 20c; 20 for 50c. This is Zantedeschia Rehmanni. 
(Tubers, blooming size, ready September to June, each 65c; 
2 for $1.15.) 
CALLA, THE SPOTTED—Ivory white flower spathes, dec- 
oratively marbled foliage. Mass it by your pool. Easy and 
good in the garden, but not recommended for forcing. 
Store over winter in cellar. Good blooming-size tubers, 3 
for 40c; 9 for $1.00. Ready March through May. This is 
Zantedeschia albo-maculata. 
CALLA, NEW CREAM—Giant flower-spathes of richest 
cream. Spectacular. Withdrawn from sale for further in¬ 
crease of stock. Will be offered next year. 
CALLA, THE WHITE—This is the wax-white, fragrant 
Calla Lily, Zantedeschia aethiopica, so much used as a pot 
or window plant. It is not so generally known that it 
may be used likewise for summer blooming in the garden. 
Seeds, per pkt. 20c. (Tubers for pot culture, ready Sep¬ 
tember through December, each 36c; 3 for 90c. Tubers for 
garden planting, reach March to May, 3 for 40c; 9 for 
$ 1 . 10 .)
