Cosmos reseed like weeds for me. I have occasionally direct sown them when I wanted to fill an empty spot in a flower bed. But see all these dwarf yellow cosmos in the right front of the bed? They were all volunteers.
Here is the latest on the 10 foot cosmose.
I sowed the seeds on May 8th.Saw them on the 18th now they are 11 inches tall.
This is fun.The neighbors cant figure me out.
I broke the news to DD .I told her "now that its too late to dig them out,there are 10 foot cosmos comming up next to your vedg garden"She was thrilled and will help me photo in September.
There might be a ladder involved.
