Cutting flowers- what annuals would be good?

Most annuals flowers with proper planting will last until the fall,however spring???Temperatures must remain above 60 degrees at night.Next planting will be based on lighting conditions which were not mentioned. Gardening needs though and planning it cannot properly be done without the prep first.Did you amend your soil?Lighting was never mentioned?

Lavender and you can cut them in fall let dry for about 2-3 weeks put in knee high stocking or material pouch tie w/ a ribbon and place in drawer/ closet/ bathroom every once in awhile crush and smell the lavender or put in jar w/tight lid open for fragrance the close after an hr or so hope this is helpful.

Hi Laura, I am not sure if this flowering plants thrive in Ontario but you can never go wrong with pansies and/or peonies. Good luck!
