OPUNTIA 
Here is a bit of the strange Cactus family; in form 
weird and interesting; in flower, gorgeously showy. The 
Opuntias have large bony seeds that take a bit longer to 
germinate than do those of other Cactus groups, but 
are particularly sure to sprout eventually, if given right 
care. Please note that several of the species offered are 
fully winter-hardy in the north, and of unique value in 
the sunny rockery, or for exotic and startling bedding ef¬ 
fects. The other kinds are for pot culture.

spine-tufts of brown wool. Blossoms rich red. Pkt. 15c.

rope-like spiny stems in branching tree form. The stems 
are sometimes made into canes. Flowers of brilliant pur¬ 
ple. This is the tallest of the relatively hardy species. Safe

position will likely stand lower temperatures. Pkt. 15c;

fruits. Pkt. of 15 seeds for 20c; 50 seeds for 55c.

clad hardiness, wintering without protection in Canada. 
Most attractive tangles of glossy green branching pads. 
Almost spineless. Particularly showy flowers of brightest 
yellow. A row of it in my trial grounds is so prolific of 
bloom that for many weeks it is a wide band of pale 
burnished gold, intermingled here and there with the warm 
wine-cup crimson of Callirhoe, strayed over from the row 
along side. Pkt. 10c; Ys oz. 30c.

ORCHIDS 
It is fully possible to grow them from seed. Naturally 
this is the way they spread in the wild. It is not particu¬ 
larly easy, though, chiefly because of the exceeding fineness 
and peculiar nature of the seeds, and the long time required 
for germination. Success in this is an achievement that 
marks one as truly an horticulturist, but beginners can 
only advance by trying, and it is interesting to experiment. 
Cultural folder sent with seed shipments contains brief 
notes in sowing of Orchid seeds under ordinary conditions. 
If you want to try the “pure culture” method that experts 
use, see the long article under “Orchids” in Bailey’s Hortus. 
This monumental horticultural reference work is accessible 
in most public libraries, or I offer it on book page of this 
catalog.

sorts, not less than twelve kinds; for growing under glass.

restrial Orchid, royal purple and pure white. Pkt. 20c. 
A mulch of straw, old burlap, or similar material,

has been sown, will conserve moisture and make for 
quicker germination. Be sure to remove mulching 
as soon as first sprout appears, else the tiny seed¬ 
lings may die.
