MAY 113 



When quite dry, they stand a moderate amount of frost. 

 Then in March they are brought out, the ground is 

 stirred and mulched, and they are taken into a greenhouse 

 and brought on a bit. In May they are thickly covered 

 with good strong horse-manure and copiously watered. 

 At the end of the month they are stood out in the open 

 on a low wall. During May, June, and July they cannot 

 have too much water ; after that they want much less, or 

 the leaves turn yellow and drop off. Campanula pyrami- 

 dalis (see * English Flower Garden '), a biennial, does well 

 in pots, if shaded blue and white both in one pot, or apart. 

 The seedlings have to be potted up in autumn (plants a 

 year old) ; as with the Canterbury Bells, if you cut 

 off the fading flowers the flowering season is much pro- 

 longed. Canterbury Bells (Campanula medium) make 

 charming pot-plants for large rooms or corridors in 

 May or June. They are annuals, and the seed can 

 be sown out of doors in March or April, keeping the 

 seedlings well thinned, transplanting in the autumn, and 

 potting-up the following spring (see 'English Flower 

 Garden '). If strong crowns of Campanula persicifolia 

 are potted up in autumn, they force beautifully in a 

 moderate greenhouse in spring, and are most satisfactory 

 for picking or otherwise. 



Some years I grow Solanum jasminoides over bent 

 wires in pots; they are rather pretty. Clethra (Sweet 

 Pepper Bush), a small North American shrub, we lifted 

 from the reserve garden in June and put into a pot, and 

 it flowered very well. The variety of plants which can 

 be experimented upon for growing in pots out of doors 

 in summer is almost endless. Love-lies-bleeding (Ama- 

 ranthus caudatus) is an annual ; but if sown in January, 

 and very well grown-on as a fine single specimen plant, 

 it looks handsome and uncommon in a green glazed 

 pot or small tub. Nothing we grow in pots is more
