246 THE TRILLIUM. 



The root is a flattish tuber, and resembles that of other 

 aroideous phmts. The only requisites for successful culture 

 are rich soil, plenty of water, and pot-room. 



It propagates freely by suckers, which should be removed 

 if a single large plant is the object ; but the better plan is to 

 keep repotting as the old pot fills with roots, and allowing 

 all the suckers to remain : a very large plant will be the 

 result, which will never be out of bloom. 



As a bedding-plant in the summer, the calla does well, 

 producing fine, healthy foliage, but not flowering freely. 

 In water-scenery, its foliage is very eifective. 



There is a variety, with foliage spotted with white, which 

 may be desirable in a collection of foliaged plants. 



The plant is a native of Africa, and is killed by the least 

 frost. 



THE TRILLIUM. 



These plants are natives of rich woods, but grow well in 

 the garden, if in deep soil, and not in a very dry situation. 

 They are among the most beautiful of spring-blooming 

 plants, and nothing can exceed the beauty of a large bed 

 of T. grandiflorum in full bloom. The corm is small, 

 roundish, and seamed, and generally deep in the ground.
