THE FLOWER GROWER'S GUIDE. 



petroleum. The oil is liable to collect on the surface of the water, and as an overdose 

 may prove fatal, this must and can be prevented by keeping the oil and water mixed by 

 forcibly returning every second syringeful to the can. Petroleum and hot water will 

 not injure the roots, but it is the usual practice to lay plants in pots on their side when 

 they are syringed, and also to syringe camellias and other smooth-leaved shrubs with clear 

 water three hours after wetting them with the petroleum mixture. Shading from bright 

 sunshine is advisable for two or three days after cleansing the plants.

CAMPANULA. 



There are three species of campanula or bell-flower that are well adapted for pot 

 culture, and these, at their best, are remarkably showy and beautiful. C. isophylla, of 

 which there is a white form — C. i. alba — is a perennial of a trailing habit of growth, 

 and one of the most attractive summer-flowering basket plants imaginable. It is this 

 species that is often met with as a window plant. C. medium, or the old Canterbury 

 Bell, has now been largely superseded by C. m. calythema, or cup-and-saucer flower, so 

 called from the fact of the flowers in their conformation much resembling a cup and 

 saucer. These flowers are principally in three distinct shades of colour — blue, white, 

 and rose, are much larger than the type, and produced in tall spreading pyramids in 

 May and June. There is also a tendency to doubling of the flowers observable, but 

 though more serviceable for cutting, these double flowers are not so handsome as the 

 single ones. C. pyramidalis blue and C. p. alba white attain a height of 4 to 6 feet, 

 and when well grown are grand plants for conservatory decoration. 



Culture. — C. isophylla may be either raised from seed or increased by division and 

 cuttings. If seed is sown in gentle heat in April and the seedlings are duly transplanted 

 an inch or two apart in pans or boxes, or placed singly in small pots of light loamy soil, the
