FLOWER SEEDS FOR FLORISTS" 
BALL CALENDULA 
D uring the depth of winter 
when the color in most 
flowers is weakest, that of 
Calendula is as cheerful and 
bright as ever. It is this rich 
warm coloring and ease of 
growth in a cool temperature 
that makes them so indispensable 
throughout mid-winter. We are 
proud of these Calendula for we 
originated and introduced all of 
them. We continue to be as 
much interested in their improve¬ 
ment as we were in originating 
them. The seed we offer you of 
these Calendula is from stock 
seed we develop in our green¬ 
houses and we feel very sure 
that the seed we supply you is 
as good as is available. 
CULTURE. For a full Christmas 
crop such as is pictured on the 
front page of this catalog, sow 
August 1. We prefer doing 
this in an outdoor frame that we 
cover with aster cloth to pre¬ 
vent the same ‘‘yellows” that 
infects asters. You can do the 
watering right thru this cloth. 
Around September 1 we trans¬ 
plant the seedlings into the flowering beds 12x12 in. We also make a sowing September 1 
that is used to follow early shaded mums. This gets in full crop in January, which is 
usually a good month. As market growers we never could make much out of a spring 
crop of Calendula, but a retail grower should get in some after mums for spring cut¬ 
ting. Less than 1% of Ball Calendula come single under favorable conditions. These 
conditions are: well enriched deep soil, cool temperature and free ventilation. Any 
check or weakening of the plant brings on single flowers. It is a jar to any plant to 
cut a heavy crop from it. For this reason singles show up some in Calendula as the 
crop becomes cut down. After the early planting is cut down, the old plants will 
break out freely again and produce a good spring crop. Should you be interested 
in further details on this crop refer to our Ball Red Book. Perhaps you have one. 
If not, it is postpaid for 20c. It is issued annually and covers the practical cultural 
details of your every day crops.
