The annual by seed in the open dry border, 

 towards the end of March ; the shrubby kinds 

 by cuttings, under a bell-glass, in April ; or 

 under a hand-light in a shady place in summer. 

 Sandy fibry loam, and a little leaf-mould ; when 

 planted out of doors, young plants must be 

 reared for saving through the winter in a cold 

 pit or greenhouse. There are many other 

 species besides the following, but they are 

 mere weeds.

 andria.} 



All yellow-flowered, except where otherwise 

 mentioned. The hardier ones flourish in 

 common and sandy loam, and the more tender 

 in loam and peat. Annuals sow in the open 

 border in March ; herbaceous sow, and divide 

 the plants in spring ; shrubs are easily divided, 

 as they stole freely, and also by seeds ; green- 

 house and frame kinds by divisions, but chiefly 

 by cuttings of young shoots, in sand, under 

 glass; most of them, if protected in winter, 

 would grow against a wall. For exposed places, 

 the following are the best shrubby ones ela- 

 tior, hircinum, calycinum, Kalmianum, and 

 prolificum,
