Seasons to Sow Flower Seeds in Central California 
> 
This list enables one to tell at a glance when the various flower seeds may be sown. As some perennials will bloom 
the same season if sown early in the year, we have stated the latest time in spring that they may be sown for this pur¬ 
pose. Several varieties of hardy annuals if sown in the fall will come into bloom earlier than if sown in the spring, even 
if tlie plants do not make much progress during the cold weather. Tender and half hardy annuals, if sown early, should 
Ik* started in a warm, sheltered position and transplanted when the cold weather is over.
