DESCRIPTIVE AND SELECTIVE. 273 



They are pretty Alpines, worthy of good positions, and 

 will do well in loam if well drained. They may be 

 raised from seed sown under glass in spring. Dal- 

 maticus, violet flowers in large clusters in early summer ; 

 Kitaibelii, blue flowers in summer, a vigorous tufty 

 species ; and Pumilio, silvery leaves, and lilac flowers 

 in early summer, are three of the best kinds. 



WALDSTEINIA. — A small genus, but containing 

 a very pretty plant in the species trifolia (three-leaved), 

 which grows about six inches high and bears yellow 

 flowers in April or May. It grows strongly, and throws 

 out runners like a Strawberry. The same trait dis- 

 tinguishes the species fragarioides (" Strawberry-like '') 

 which bears yellow flowers in early summer. They 

 thrive in ordinary soil in sunny places, and may be 

 propagated by division in spring. 



WALLFLOWER. — See Cheiranthus. 



WULFENIA. — ^Two species of this genus are grown, 

 namely. Anther stiana and carinthiacUy both of which 

 produce blue flowers in July. They will thrive in moist 

 but well-drained loam, and may be propagated by 

 seeds or division in spring. 



ZA USCHNERIA CALIFORNICA .—A graceful 

 and brilliant American plant, well deserving the name 

 of Calif ornian Fuchsia. It produces its scarlet flowers 

 on stems a foot to eighteen inches high in Summer. It 

 is not perfectly hardy, and should be given a warm 

 position, and sandy, well-drained loam. It may be 

 raised from seed sown under glass in summer, and 

 the young plants kept in a frame through the 

 winter.
