I am planning a white garden this year and would like to plant white cosmos. I have other cosmos fifteen to twenty feet away. If I plant the white cosmos will I be invaded with colors next year? |
The only way you'll get a mix of cosmos flower colors is if the white cosmos cross pollinate with the other colors, set seeds and the seeds fall to the ground, over winter and come up next year. Cosmos will self-sow seeds in this way, but you can control this by cultivating any new seedlings that come up in spring as soon as you notice them. Then, after a few weeks, plant your desired mix of cosmos colors and the bed should be true to color. |
