102 THE SEED-GROWER. 
in autumn, they usually flower the next season, but if 
divided and set out in spring, they rarely flower before 
the following year. 
RICHARDIA OR CALLA LILY. 
This calla is propagated from offsets. In California, 
the plant grows out of doors all the year round. In 
that climate, when proper attention is given to its cul- 
ture, the tops are cut off in July, within a couple inches 
of the surface of the ground, after which the plant takes 
a rest, and in course of a month or so it makes a fresh 
start, renewing its growth and bloom. The larger roots 
are the result of three or four years’ growth, plants not 
being disturbed during that period. 
The roots are usually dug in June and July. After 
which the tops are cut off close to the bulb, taking care 
not to injure the centre or heart-germ. The roots are 
then trimmed of side shoots and spread thinly on 
shallow crates or trays placed in a shed and allowed 
thus to remain for several weeks till considered cured, 
or dry enough for shipment to a distance. 
TIGRIDIA OR TIGER FLOWER. 
Propagated by offsets which are planted in spring. 
After a killing frost in the fall, the bulbs are lifted, the 
tops cut off, and after being dried, they may be kept in 
ventilated boxes in a cellar, or in a dry room safe from 
frost, or they may be hung up tied in bunches with the 
tops left on. 
TULIP. 
Propagated from offsets. As with the hyacinth, the 
flowers should be cut as soon as they develop, so as to 
throw the strength of the plant to the formation of the 
bulb. This will also mature the bulbs quicker, so that
