Biennials may all be raised from seed, which is produce 1 

 abundantly by most of the species ; and the best time for 

 sowing them is as soon as the seed is ripe. With those 

 that flower very late in the season, however, it would be 

 injudicious to sow the seed at the time of ripening, and it 

 is much better to preserve it till the spring. The seed 

 should be sown in shallow drills, or in small beds of four 

 or five feet in width, in an exposed situation ; and the young 

 plants should be thinned to a proper distance from each 

 other as soon as they appear, that they may not gi^ow too 

 weak and sickly, also taking care to remove all weeds. If 

 the seed is sown ea.rly in the autumn, the plants will be 

 large enough to remove to the borders in the spring, and, 

 like perennials, they should be taken up with as much soil 

 as possible about the roots. But if they are not sown till 

 the spring, they should be retained in the seed-bed till the 

 early part of the succeeding spring, when they may then 

 be removed to the borders in which they are intended to 

 flower. Those which are sown early in the autumn, will 

 frequently flower in the following summer ; but, if they 

 are not sufficiently strong, the tendency to flower should 

 be timely checked, and they will blossom much finer in 

 the ensuing year. 



Though all biennials are capable of being multiplied from 

 seed, there are ma.ny which would produce difi^ereut varie- 

 ties from seed, and consequently very fine sorts of such can 

 only be increased by cuttings. This is the case with many 

 of the beautiful varieties of snapdragon ; and by frequently 

 taking off* cuttings from them, and striking them under a
