SWEET WILLIAM. 



— Ornamental slirubs, with white ' 

 flowers, natives of Europe and North 

 America, which grow best in sandy- 

 peat or heath-mould, and flower i 

 freely. They are propagated by i 

 layers. 



Succory. — CicJwrmm Fntyhus \ 

 is a British plant, with brilliant blue 

 flowers, which grows freely in sandy 

 soils, and which may be grown with 

 the greatest ease in gardens. \ 



Succulent Plants are those | 

 which have both their stems and 

 leaves provided with so few stomata, 

 as to be able to retain a great portion 

 of the moisture which is evaporated 

 by other plants. These plants are 

 generally natives of sandy deserts, 

 where for half the year they are 

 entirely destitute of water, and where 

 their capability of retaining moisture 

 is necessary to keep them ahve. 

 When grown in Europe, they are 

 well adapted for sitting-rooms, as 

 they are capable of bearing a greater 

 degree of dryness in the air than 

 most other plants ; but they are very 

 liable to be injured by too much 

 water, as in the cloudy atmosphere 

 of England their stomata are not 

 sufiiciently numerous to enable them 

 to throw it off, and it rots them, or, 

 as gardeners express it, they damp off. 

 All succulent plants, when grown in 

 pots, should have abundant drain- 

 age, and should never be suffered to 

 stand with water in the saucer ; and 

 the soil in which they are grown 

 should be mixed with sand or lime- 

 rubbish to keep it open, and in a 

 state fit for their roots to penetrate 

 through it. 



SuFERUTicosE PLANTS are those 

 which are shrubby at the base, but 

 herbaceous in the upper part of the 

 stem ; such as the common Wall- 

 flower, theBrompton or Queen Stock, 

 Iberis senipervlrens, &c.

 British gardens, and which should ■ 

 be grown in sandy loam.

Sweet William. — Didnthus lar- 

 batas. — This plant is quite hardy in 

 British gardens. The flowers are pro- 

 duced in large clusters, each separate 

 flower resembling a small Chinese 

 Pink, except in the calycine scales 

 or bracts, which are very long and 

 sharply pointed. Some of the va- 

 rieties are very beautiful, particularly 

 those with deep rose-coloured flowers, 

 and one the flowers of which are white, 

 spotted with pale pink. The finest 

 varieties I ever saw of this plant were 

 in Scotland, at Milton-Lockhart, on
