Biennials live for approximately two growing seasons, make seeds, and then die.

List of Biennials

• Hollyhock
• Honesty
• Poppy
• Stock
• Sweet William

This list came from Horticulture: The Art and Science of Smart Gardening website.  This is just a list of popular biennials and not a complete list.  I encourage you to do a little research into these kinds of flowers.  Some biennials are grown as annuals like the Blue Bedder; while others are grown as perennials such as the Delphinium ‘Centurion Sky Blue’.   It pays to do a little research and find out which is which because some biennials will re-seed themselves acting as perennials, but you don’t want to be surprised by an annual when it blooms the second year and then suddenly dies back and never returns.
