VANILLA 
Vanda Suaris—Tricolor type. 
There are but a few species in this genus, all of 
which are climbers. Vanilla is, perhaps, the only 
genus of orchidaceous plants that has an economic 
value. The fruits of the various species produce the 
vanilla of commerce used so extensively for flavoring. 
The plants require strong heat and an abundance of 
water when growing, and should be potted small in 
peat and sphagnum and trained against a wall. 
Planifolia, (Central America) —Summer-fall. The flowers 
are a beautiful citron yellow and very showy. 
Single stems, 2-4' 3.50 
Planifolia —Longer stems. 4.00- 7.50 
Planifolia var. Varigata —Even out of flower a beautiful 
climber with its fleshy green leaves variagated with 
white. Single stems, 2-4' 4.00 
Planifolia var. Varigata —Longer stems. 4.50- 7.50 
ZYGOPETALUM 
Mackayii, (Brazil) —Autumn. A wonderfully attractive 
orchid of easy culture which should be included in 
every collection. Its marvelous fragrance alone makes 
it a plant to be desired and its beautiful spikes with 
contrasting colors of purples, whites and lined with 
violet purple, makes it doubly desirable. While sev¬ 
eral authorities advise rich composts and heat, we find 
our Zygopetalums do best with a good supply of drain¬ 
age about % good osmunda fibre and Vi live sphag¬ 
num moss. In the late spring, we place the plants 
outside under slat shades on a well drained bed of 
stone and leave them until late fall, when we place 
them in a cool position. When growing they require 
considerable water. 3-4 bulbs 10.00 
Mackayii —Larger and stronger plants. 12.50-17.50 
HOUSE CULTURE 
We believe the following suggestions, in ad¬ 
dition to "General Culture" will be of value to 
those who desire to grow a few Orchid plants 
in the house. 
An air-conditioned home is quite ideal for 
growing plants, provided there is a sunny 
room or a bay window having a favorable 
exposure. There is a regulated amount of hu¬ 
midity in an air-conditioned house that is not 
present in homes heated with hot water or 
steam, unless the latter two are equipped with 
humidifiers. Humidity is quite necessary and 
is maintained to varying extents in greenhouses 
through syringing and damping down. Un¬ 
fortunately, in a home, we cannot do this and 
so must find other ways to give the plants the 
humidity they lack. We suggest a shallow 
tray about six inches deep having a metal 
lining with a vent in the bottom, and filled 
with about four inches of nice, clean pebbles 
or half-inch stone. Two inches above this, 
place a rack, preferably of thin wood slats, 
spaced one-half inch apart. The Orchids should 
be placed on this slat top. By keeping the 
stone and slat top wet, the plants receive a 
certain amount of humidity. 
Plants may require more water in the Winter 
in the home than they do in the Greenhouse. 
For this reason they should be looked over at 
least once a week for a good watering. A hand 
sprayer is handy for syringing and can be used 
on the foliage several times on nice days. 
Through the Summer or times when the home 
is not artificially heated, it will often be found 
the plants take longer to dry out, and of course 
require less water if such is the case. 
Orchid plants do very well out of doors 
through the Summer but cannot stand full sun. 
Moderate shade from a tree, or a framework 
of slats gives a very nice light. They will re¬ 
quire considerably more water and syringing 
of the foliage outside than they will in the 
house. We have noted in our recommenda¬ 
tions those varieties best suited for this culture. 
VARIETIES RECOMMENDED FOR HOUSE CULTURE 
Cypripediums —All of the varieties listed under Collection 
No. 1, will do well in the Home. Each $ 3.50.-3 for $10.00 
Selenipediums —All listed in Collection No. 2, are recom¬ 
mended. Each $ 3.50; 3 for $10.00 
Cattleya Species —As listed in Collection No. 10 are recom¬ 
mended. Each $ 6.00; 3 for $17.50 
Cymbidiums —Are recommended provided they can be 
grown outside through the Summer, as detailed under 
Cymbidium Culture. Each $12.50; 3 for $35.00 
Cattleya Hybrids —Will do well but because of their higher 
cost we would recommend other types to start with.
