What is the difference between a hardy and a half-hardy annual?
Posted by Suttons Staff on 24 June 2013 11:11 AM
Hardy annuals are sown outdoors in late March and April when conditions allow and in some cases a sowing can be made outdoors during September for early flowering.  

Half-hardy annuals require warmth to develop.  The seeds are sown in a greenhouse or indoors on a windowsill normally from January to April depending on the item being sown.
