How many colors of the hollhock are there? Can they cross-polinate to create new colors? We have a variety of colors, however, we did not plant all of the colors and different shades that have come up and bloomed this year. How does this happen? Thank you for your help. |
Hollyhocks are well known for cross-hybridization. The seeds of one plant may produce a myriad of flower variations. All are extremely beautiful. I always anxiously wait to see the colors from a new batch of hollyhock seedlings because each one is lovelier than the next. |
