I enjoy! growing zinnias and marigolds in containers.
You will have color and blooms right up to your first frost.
Here is a photo of white wedding zinnia.
very white in color and is pretty!
I have grown hardy hibisus from seeds.the seeds need cold stratified before starting the seeds.I chill the seeds in the refrigerator and nick and soak the seed before sowing.
Quick germination of the seeds.
