winter, and kept there at least until April, 

 when they may be removed to their bloom- 

 ing quarters. It is desirable to winter 

 some stocks in a cold frame in pots, lest 

 the winter prove too inclement for them 

 and they be carried off by frost.

Bentha'mia (/ ord. Corna'ceae). 



An ornamental profuse-flowering half- 

 hardy shrub, the flowers succeeded by 

 reddish-yellow, strawberry-like fruit, which 

 is eatable. It may be grown in the open 

 air in South Devon, Cornwall, or the Scilly 

 Isles, but is scarcely suitable for higher 

 ' latitudes unless grown against a south wall 

 and in places near the south coast. It likes 

 a rich moist loam, and may be propagated 

 by seeds sown soon after attaining ripeness 

 in a cool greenhouse, or by layers put down 

 about September or October. A good 

 example is found in Benthamia fragifera, 

 a species with large cream-coloured flowers, 

 10 feet in height. 



Biennials, List of. 



The following is a brief list of biennials, 

 desirable for the garden and borders. 

 Those that are more hardy than the 

 generality of biennials, and need no pro- 

 tection, are distinguished by a star. Those 

 that are not so marked should be protected 

 in cold pits or frames during the winter, 

 and not planted out until all fear of injury 

 fiomi frost has passed. Stocks should be 

 placed in a sheltered border during the

Biennials, Management of, etc. 



The difference between annuals and 

 biennials consists in their nature and 

 habit only. The former grows flowers, 

 yields seeds for its reproduction, and dies 

 in the same year ; biennials, on the 

 contrary, are sown and grow in the first 

 year of their existence, but do not come 

 to maturity until the second, when they 

 flower, produce seed, and die. It is but 

 few, if any, annuals that can be propagated 

 by cuttings ; but biennials, as, for example, 

 the Sweet William, may be preserved, and 

 the possession of any well-marked variety 

 maintained by pulling down layers and 

 taking off shoots from the base of the 

 plant. Although this and other plants of 

 the same kind, strictly speaking, are bi- 

 ennials, yet, from their capability of repro-
