CENTURY PLANTS — CHRYSANTHEMUMS 365 



to a collection, and may be used through the summer as noted above 

 or plunged with cactus in a bed of tropical plants. All succeed well in 

 loam and sand in equal parts, with a little leafmold in the case of the 

 small varieties. 



The more common species are propagated by suckers from around 

 the base of the established plants. A few kinds having no suckers 

 must be grown from seed. 



As to watering, they demand no special care. Agaves will not 

 stand frost to any extent. 



When the head throws up its great stem and blooms, it may ex- 

 haust itself and die; but this may be far short of a century. Some 

 species bloom more than once. 



Chrysanthemums are of many kinds, some being annual flower- 

 garden plants, some perennial border subjects, and one form is the 

 universal florists' plant. In chrysanthemums are now included the 

 pyrethrums. 



The annual chrysanthemums must not be confounded with the well- 

 known fall-flowering kinds, as they will prove a disappointment if 

 one expects large flowers of all colors and shapes. The annuals are 

 mostly coarse-growing plants, with an abundance of bloom and a rank 

 smell. The flowers are single in most cases, and not very lasting. 

 They are useful for massing and also for cut-flowers. They are among 

 the easiest of hardy annuals to grow. The stoniest part of the garden 

 will usually suit them. Colors white and shades of yellow, the flowers 

 daisy-like ; 1-3 ft. 



Amongst perennial kinds. Chrysanthemum frutescens is the well- 

 known Paris daisy or marguerite, one of the most popular of the genus. 

 This makes a good pot-plant for the window-garden, blooming through- 

 out the winter and spring months. It is usually propagated by cut- 

 tings, which, if taken in spring, will give large blooming plants for the 

 next winter. Gradually transfer to larger pots or boxes, until the 

 plants finally stand in 6-inch or 8-inch pots or in small soap boxes. 

 There is a fine yellow-flowered variety. The marguerite daisy is much 

 grown out-of-doors in California. 



The hardy perennial kinds are small-flowered, late-blooming plants, 

 known to many old people as ''artemisias." They have been
