KINDS OF PLANTS 



HARDY PERENNIALS are plants that with- 

 stand the winter in the ground and live for 

 years, often indefinitely. They form increasingly large 

 clumps which may be divided from time to time to 

 make new plants, and these may be transplanted as 

 desired, usually in the fall. Perennials may also be 

 raised from seed planted in the spring or in late sum- 

 mer and will bloom the following season. Hardy 

 Perennials include Trees, Shrubs and Herbs, and do 

 not require a winter covering. 



Hardy Annuals are plants that are grown from 

 seed in the spring, last through several months of sum- 

 mer, and then die. The seeds may be sown in the open 

 groimd in April or in May, or under glass frames or in 

 flat boxes indoors in late February or March. 



Hardy Biennials are sown one year, bloom the 

 next year, and then die. These should have a light 

 winter protection of straw, or leaves held down with 

 brush. The seeds are sown the same as annuals. 



Half-hardy Perennials and half-hardy bien- 

 nials are usually started under glass, but may be sown
