into three winter night temperature 
groups: 
1. 65° to 70° NIGHT TEMPERAT URE 
WARM GROWING CRCHIDS, Small 
seedlings of all varieties of orchids, 
Phalaenopsis, certainvarieties of 
Vandas, and many others, thrive. 
and grow wellinthis temperature. 
2. 58°to 62° NIGHT TEMPERATURE 
ORCHIDS REQUIRING INTER - 
MEDIATE TEMPERATURE. The 
cattleya varieties of orchids which 
produce the lavender, whites, and 
white with colored lip, do their 
best in this temperature. These 
are the orchid blooms most gerer- 
ally seen in corsages.

COOL GROWING ORCHIDS,Cym- 
bidiums, Zygopetalums, certain 
varieties of Odontoglossims, some 
varieties of Dendrohiums, Vands,

While the home is satisfactory for 
growing many varieties of orchids, 
we at RIVERMONT suggest that the 
beginner confine his first orchids 
to the intermediate type which do 
their bestin anight temperature rang- 
ing between 58 to 62 degrees Fahren- 
heit. After some experience on can 
then try his luckat several varieties.
