August in the green-house, if sown at two different seasons. 

 The first sowing should take place about the beginning of 

 September — the second about the middle of February or 

 beginning of March ; the first crop of plants flowering in 

 May and June, the other in the autumn. The seeds should 

 be sown in pots, and placed in the green-house, in a mixture 

 of loam, sandy peat, and leaf-mould ; the young plants 

 should be potted off when rather small — for if allowed to 

 remain long in the seed pots they get stunted — into sixty 

 pots, putting two plants into each pot close to the side, shift- 

 ing them into larger pots as they require it, always keeping 

 them near the glass in a dry airy part of the green-house. 

 The plants blossom in the greatest perfection in the green- 

 house in summer, but will grow and flower tolerably well if 

 planted in the open border, not however earlier than the end 

 of May, for a slight frost is fatal to them ; in the latter 

 situation they are most likely to produce seeds. When 

 grown in the green-house they require particular attention, 

 as too much or too little watering will in a few hours de- 

 stroy the healthiest plants ; particular care should therefore 

 be taken to drain the pots carefully at each shifting, and not 

 to give too great a shift at any one time.
