I know Zinnias are common, not as fancy as Roses or anything like that. But, I love them, never been able to grow them before. These I grew from seeds that my sister gave me. She got them from an elderly sweet man she met at a garage sale and he gave her a large mason jar full of seeds. She kept them but never used them. She said I could have them. All I did was just scattered them, no special soil, just in my soil. They are so beautiful and they make great cut flowers, as long as you keep changing the water.
