First cosmos flowers are starting to bloom. The ones I have gotten from my mom always go first. The others follow a month later in August.
I have been trying to find an early blooming variety with no luck. Simply because the summers are so short up here in the north.
This far I have not had any luck. My luck might change this year. A new variety is already making buds. We will see.
If I have no success then I just give up and continue with the one from mom. One variety is enough if it is a good one like I now have.
