THE TRILLIUM. 247 



All are perfectly hardy. They are propagated by division 

 or by seed, which vegetates with difficulty, and may be 

 transplanted either in early spring, before blooming, or in 

 autumn, when the foliage decays. The fruit is a red or 

 purple berry. All are natives of North America. The 

 species are, 



T. cernuum. Flower white, green, and purple centre, 

 nodding, and hidden beneath the leaves ; the least handsome 

 species, but very easily grown. 



T. sessile. A low-growing species, with dark-reddish 

 flowers and variegated foliage. 



T. pictum or erythrocarpum. Flower white, with lake 

 centre. Rather difficult to cultivate ; does best in moist 

 peat-soil. 



T. grandiflorum. A noble species, with large white 

 flowers, changing to rose-color. 



T. erectum. Flowers brownish purple, and with a dis- 

 agreeable odor. 



There are also other species.
