BIENNIALS 



A biennial plant lives for two years. Leaves and stems are 

 produced in the first year, and flowers in the second year. The 

 seeds are sown in a nursery bed in May. As soon as they can 

 be handled they are transplanted to a second bed in rows, allow- 

 ing 6 inches all round each plant. In the September of the 

 same year they are again transplanted, this time to their permanent 

 quarters. The most suitable biennials for growth in the school 

 garden are Wallflowers (18 in.), Sweet Williams (18 in.), Fox- 

 gloves (36 in.), Canterbury Bells (36 in.), and Cornflowers (24 in.).
