A very handsome, hardy, sufFruticose plant, with purple flow- 

 ers, growing about 1 ft. in height, and requiring the same treat- 

 ment as Pentsteinon Scolder/. It may either be grown in peat 

 or in rich garden soil. [Dot. Reg., March.)

A splendid plant, and one of such easy cultivation, that it 

 might have a place, during summer, in every flower-border and in 

 every cottage garden. The reader will liave a very imperfect 

 idea of the beauty of this plant from Mr. Paxton's figure; but 

 it is correctly described, as "differing from ail other snapdragons 

 in the colours of its flowers, which approximate in beauty to the 

 choicest carnation." It is exceedingly liable to sport, and to 

 show pure white flowers, or white, merely spotted with red, in- 

 stead of being striped. The following directions are given for 

 causing the plant to flower from the commencement of the spring 

 till the close of the autumn : — 



" In the month of September, cuttings should be taken of the young shoots 

 of those plants which are growing in the open border ; and, after planting them 

 in pots, in a light soil, they should be placed in a slight heat till they have 

 struck ; when they should be potted singly into small pots, and kept in a 

 gentle heat, till they have become established, and then removed to a green- 

 house, and afterwards to a cold-frame ; where they may be kept through the 

 ■winter, with a trifling protection from frost. Early in the spring, they will 

 require shifting into larger pots ; and, as soon as the weather will permit, they 

 should be planted out into the open border, in which situation, they'will speed- 

 ily produce their flowers. As soon as the plants above mentioned have 

 formed lateral shoots, a few of these should be taken off for cuttings, and 

 struck in a similar manner to those before alluded to. Again, other cuttings 

 may be taken off each month; and by this practice a continual succession of 

 flowers may be obtained. Besides this, the plants should never be suffered to 

 ripen their seeds; and if the flowers are constantly plucked off" as soon as they 

 begin to decay, an abundance of new flowers will speedily be formed. This 

 plant will not endure the open air in the winter months; therefore, it is better 

 to raise young plants each season, in the manner above directed, more es- 

 pecially as these latter will flower in much greater perfection than the old 

 ones. Plants of it kept in pots, in the green-house, will have a truly interest- 

 ing appearance, and flower very abundantly at almost all seasons of the year."
