I love volunteer flowers! Any cut flower that I don’t have to seed start again is a welcome relief from the work of flower farming. It also sweetens the deal when I can arrange with flowers that grow on their own, as it makes the money I spent on special varieties the previous growing season feel worth it. Who doesn’t love free flowers?
Fall can be an incredibly busy time of year, so it’s easy to forget to seed save. Luck for you, if you plant the cut flowers in this list, you won’t really have to worry about it! In my cold climate cutting garden, these flowers reliably reseed themselves year after year and are a welcome sight each growing season.
How to encourage cut flowers to reseed
You can encourage your cut flowers to reseed by allowing some flowers to reach complete maturity. Also, in fall, make sure you don’t remove dead flowers from your cutting garden! This ensures you’ll have the best chance of seeing volunteers the following growing season, and you should be pleasantly surprised when these plants reappear in May. If it’s a dry year, water the area regularly to encourage germination. Other than that, the flowers basically do the work for you!
Self-sowing flowers for cold climates
These flowers are not perennials, but they almost behave like them since they’re such reliable re-seeders. Make sure you plant these annuals in a location where you hope to have them for years to come!
Amaranth thrives where other flowers fail. This cut-and-come-again flower is one of my favourites for arranging!
Bachelor’s Buttons come in gorgeous shades of blue, purple, pink, and white and are a favourite flower for pollinators!
3. Bells of Ireland
Bells of Ireland can be tough to germinate. Just letting them reseed is sometimes a more reliable method!
Calendula flowers are easy to save seeds from and are a welcome volunteer in the cutting garden. They are beautiful in bouquets and, if processed properly, can be used in homemade beauty products, teas, and more!
Feverfew is actually a perennial in Zone 3, so it can both reseed and become a perennial plant!
8. Frosted Explosion Grass
I love Frosted Explosion Grass and use it in as many bouquets as possible.
Garden Huckleberries are best consumed cooked and sweetened. However, my favourite way to use them is to add a pop of unexpected texture to cut flower arrangements!
Nigella are cool-loving cut flowers that can be harvested for their blooms or their seed pods.
Poppies are cold-hardy and perfect for cut flower growers in Zone 3 or similar climates.

Saponaria is my favourite substitute for Baby’s Breath. It’s easy to grow and is extremely cold-tolerant.
