54 ALSTRCE.MERIA 



tiou, and at all times iluring their growth the roots must 

 have an abundance of water. In fact, there is little use 

 in attempting their cultivation out-of-doors where these 

 conditions cannot be given. In colder climates, the Al 

 stroemerias can be grown very successfully by planting 

 out in spring, and, as soon as they die down, lift, am 

 keep overwinter in a place from which frost is excluded 

 An annual lifting, or, when grown in pots, an annual 

 shaking-out, should be given, because they Increase to 

 such an extent that the younger and smaller crowns are 

 apt to take the nourishment from the large, flowering 

 crowns. The largest ones ought to be separated from 

 the smaller ones, and either grown in pots or planted 

 outside when the pr'ipor tiiiir arrives. In this way the 



genus will become n Ii in<in- popular than it now is, 



either for cuttin;.' mi i.r th. , lie. .ration of the border.

for at least 15 inches. The tubers 



are slightly egg-shaped, attached

 and also from near the growing 

 points of the crowns. 



One of the best for greenhouse 

 work is A. Pelegrina, var. a!ba. 

 Other kinds wliich may be con- 

 sidered tender north of Washing- 

 ton are A. hfPmanfha, A. versicolor (or 

 Peruviana) and its forms, A. Uookerii 

 and A . violacea. Some of the Van Houtte 

 hybrids, raised from Hookerii and hieraan- 

 tha, are extremely pretty, but, with the 

 others, they are rather unsuitable for pot- 

 culture, owing to the peculiar formation 

 of the roots. 



The species are easily raised from seeds, 



which should be sown rather thinly in 



deep pans, and allowed to remain without 



pricking off or shifting for the first season.
