FLORAL DISPLAY FOR DECEMBER 
During the month of December the display of flowering 
plants in the floral display house will typify the holiday sea- 
son, the predominating colors being red and white. About 
2,000 poinsettias, varying in size from the dwarf varieties 
about a foot or less in height to the tree plants as high as 
twelve feet, will constitute the greater part of this exhibit. 
Interesting variations of the poinsettia being shown in St. 
Louis for the first time are the white and pink-flowered var- 
leties. As a matter of fact, however, the flowers of the poin- 
settias are neither white, pink, nor red but a sort of greenish 
yellow, the part of the plant usually called the flower being 
the conspicuous whorl of leaves immediately surrounding the 
cluster of flowers in the center. 
As a setting for the poinsettias about 2,000 potted plants 
of the variegated stevia are being used. These plants have 
rather insignificant white flowers, but because of the loose- 
ness and natural gracefulness of the sprays they tend to set 
off to advantage the form and color of the poinsettia. In ad- 
dition to the stevia about 2,000 bulbs of the paper-white nar- 
cissus will be on display, and besides adding to the white 
color of the exhibit will fill the house with fragrance. A few 
cyclamen in red, white, and lavender will be shown, and a 
few groups of the yellow-flowered reinwardtia will also be
