Hardy Annuals and Biennials are plants which do not 
require shelter or protection from an ordinary amount of frost 
when under average cultural conditions. 
Tender Annuals are well known in Asters, Ten-week 
Stocks, Zinnias, Helichrysums, and Phlox Drummondii. 
Tender Biennials are of no 
real value to the small 
gardener, though no well-managed flower-garden would be 
complete without some representatives.
