do columbine flowers spread

Question

Do the columbine flowers spread each year or do they remain as one bunch or plant?

Answer 1

Columbine flowers will spread if the flowers are left on the plants to go to seed. The seeds will spread and are easily germinated.
If you want to keep the plants confined, just dead head the flowers before they go to seed.
