GREENHOUSE PLANTS FROM SEEDS 61 



not make flowering plants until the autumn of the next 

 year, but are worth the waiting for. They may be 

 raised in a cold frame, the young plants being grown on 

 so that they occupy fuur-inch pots for the winter, which 

 they should spend in a cool house where they may be kept 

 rather dry at the root. In early spring, pot on into six- 

 inch pots, potting very firmly, and from these again when 

 full of roots into eight-inch or nine-inch pots. This last 

 potting should take place just as the stems appear to 

 be lengthening, which will be an indication of running 

 to flower ; they will then give a fine display of flowers, 

 and if the earlier ones are picked off as they fade, 

 others will come on in succession. There are both blue 

 and white flowered forms of this fine Campanula, and 

 seedsmen also sell now a dwarfer form which has been 

 selected and which is useful for small houses. This 

 Campanula is hardy if it can be kept dry through the 

 winter. It may be wintered outside in the garden 

 frame, if the lights are water-tight, provided the pots 

 are plunged to their rims in ashes. 



Ce/osias. — The very elegantly plumed Celosia pyra- 

 midalis is here intended, but with it may be classed 

 the ever gorgeous and quaint Cockscombs which many 

 people delight in growing. Except in the early stages, 

 they may be grown in the greenhouse, where they are 

 very attractive and bright through the autumn. To 

 raise them, one must command a night temperature of 

 about 60 deg., more rather than less, and this may be 

 produced by making up a hot-bed of stable manure 

 and leaves on which to place a garden frame. Such a 

 hot-bed is one of the greatest boons to the owner of 

 a garden which does not contain a hot-house, for in 

 it may be raised and propagated very many things im- 

 possible without some such aid. 



Sow the seeds in March or early in April in well 

 drained pots of light soil containing a considerable
