AMERICAN BULBS UNDER GLASS 
13 
It is unnecessary to comment on the other bulbs. The character 
and behavior of this one will illustrate very definitely the causes of 
some complaints regarding the Paperwhite Grandiflora grown in 
this country and forced under glass. There is too great a tendency 
to put large split bulbs on the market, whereas the bulbs that give 
the best results are those which are round, firm, single nosed, and 
ranging in size from 12 to 16 centimeters. When these and these only 
are forced they are successful. All others should be planted to 
increase the stock.

One seemed to be a 
double Chinese lily. 
Bulbs too small. 
Fine and strong. 
Two bulbs did not 
flower. One 4-flow- 
ered Chinese lily be- 
sides the above. 
As good as any im- 
ported stock. 
Mostly 4 to 6 flowered. 
One Chinese lily pro- 
duced a stalk with 4 
flowers. 
Samples showing dif- 
ferent types of 
growth. 
Five are Chinese lilies, 
4 to 9 flowered. Va- 
riable in type of 
flower. Not all of 
the Paperwhite 
Grandiflora type. 
It may not be amiss here to say a word about the production of 
such bulbs. It is evident that the best time to begin the selection 
of marketable bulbs is before they are planted instead of after they 
are dug ; in other words, the bulbs should be sized into different cate- 
gories before planting. There will be three or possibly four sizes: 
One consisting of big bulbs in which the divisions are laid down but 
not separated enough to be pulled apart; the others of two or three 
sizes of slabs, the largest of which will grow to 12 to 15 centimeter 
round bulbs in one year and the others a year later. When this 
sizing occurs at planting time and the growing is well done, the larg- 
est splits should practically all be turned off after one year's culture. 
If the bulbs are mixed and all sizes are grown together, it is something 
of a task to pick out by hand the bulbs which should go on the 
market. Besides this, sizing the stocks gives an opportunity for 
a better distribution of plant material on the land. 
The production of stocks of Paperwhite Grandiflora is being 
attempted on the California coast from Humboldt County south, in 
southern Texas, and generally along the coast of the Gulf States. 
The greatest activity just now is in Florida and as far north on the 
Atlantic coast as southeastern South Carolina. Both the Paperwhite
