ALYSSUM 



ALYSSUM (classical name). Cruciferw. Low plants, 

 mostly perennials and nsed for rockwork. The Sweet 

 Alyssum is one of the commonest annuals, grown both 

 in the open ami forced 

 .fSife in benches, beds or 

 ^■JV^ pots. It is of the easi- 

 est culture, either in- 

 doors or out. The com- 

 pact vars. are most 

 prized for pot-culture. 

 Under glass, requires 

 temperature of a car- 

 nation house. It will 

 stand considerable 

 frost in the open, and 

 may be sown early ; it blooms all summer, and until 

 killed by winter. Useful for window gardens and bas- 

 kets. For winter bloom, sow seeds late in Aug. or in 

 Sept. When blooms begin to fail, cut back the plant, and 

 it will bloom again. The perennial species are usually 

 prop, by dividing the roots ; also by cuttings and seeds.

AMAEANTUS (Greek, unfading). Amarantucece.

 rich soil the lvs. become very large but iisually lack in

 A. tricolor (G.W. 6; 709). A form with fiery red lvs. is 

 known as A. hicolor. Various dwarf and compact bed- 

 ding forms. Used more for foliage than for fl. panicles. 

 Asian. 



Other garden Amaranthuses are A, Abyssinicus, 

 dark red; A. gibbdsus, Hort., a form of A . panieulatns ; 

 A. Hhideri, probably a hybrid with A. snlicifolius, or a

var. of it, with long-drooping, orown Ivs., and tall, pyra- 

 midal stature; A. Odrdoni. or Sunrise, with bronzy
