ALSTRCEMERIA 



tion, and at all times (luring 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, and 

 keep over winter 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 proper time arrives. In this way the 

 genus will become much more popular than it now is 

 either for cutting or for the decoration of the border 

 The soil best suited to their requirements is largely com 

 posed of vegetable humus; when this is not to be had 

 old, well-decayed cow or stable manure should be incor 

 porated with the soil. When they 

 are planted outside, the tubers 

 should be put deep in the ground, 

 and the .soil should be well worked 

 for at least 15 inches. The tubers 

 are slightly egg-shaped, attached 

 to a common stem ; the roots are 

 made from the ends of the tubers, 

 and also from near the growing 

 points of the crowns. 



One of the best for greenhouse 

 work is A. Pelegrina, var. alba. 

 Other kinds wliich may be con- 

 sidered tender north of Washing- 

 ton are A. hiemtuitha, A. versicolor (or 

 Peritriana) and its forms, A. Hookerli 

 and A.vlolncea. Some of the Van Hoiitte 

 hybrids, raised from Hookerii and hjemau- 

 tlia, 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 oil or shifting for the first season.
