 are flat, dwarf, compact, commuiily tvi ii,'niii |ilauts, 

 with dark green Ivs., completely coviti'iI witli liroad, 

 flat or elongated clusters of irregular cruciferous fls. 

 in spring. 



The annuals are showy branching plants, 6-18 in. 

 high, much grown in masses in beds or for edging. 

 Florists grow them also, especially the white varieties, 

 for cut-flowers. They are of easy cultivation, and suc- 

 ceed in any rich garden soil, in a place exposed to light 

 and air. They are propagated by seeds, which may be 

 sown at any season, in the house or open ground, but 

 particularly in the fall when the climate permits, or as 

 early as possible in spring, in rows 6-8 in. apart where 

 the plants are to grow, the plants being thinned later to 

 4 in. apart in the row. The finest display is attained 

 from autumn-sown plants, which flower from iMay to 

 July. If seed is sown in autumn, the plants should be 

 slightly protected from the sun during winter. Seeds 

 sown early in the spring bloom from July to September.

 is warm. The nam.' ('air.lvluri was given because the 

 fls. appear in tufts aud because the first introduced 

 species, /. umbellata, was brought from Candia. 



The subshrubby species are adapted to the front of 

 shrubberies, where they connect taller plants with the 

 surrounding lawn. They may appear in separate clumps, 

 in broad masses, or may mingle with other genera in 

 the herbaceous border. They are suited to rockeries, 

 and hang well over walls and ledges. They are to be 

 treated much like herbaceous perennials. They are 

 plants of refinement, and are pleasing when close to the 

 observer. They are useful and popular for cut-flowers, 

 are easily forced into bloom in winter, and are adapted 

 to pot and pan culture. They are easily propagated. 

 The perennial Iberis succeed best when let alone. Once 

 planted and not disturbed, they soon form a dense foli- 

 age. They are the best spreading, dwarf plants with 

 white flowers.

 The common white-fld. annual Candytuft is /. amara. 

 The common annual kinds with colored fls. are /. um- 

 bellata. The common perennial kind is /. sempervirens. 

 The clusters of some kinds remain rather flat-topped 

 when they run to seed, while the clusters of other 

 kinds lengthen after flowering. This is expressed in 

 technical language under A and aa in the key which 

 follows :
