I received a pack of zinnia seeds in 2010. In 2013 I planted them not knowing what they were for sure. They really bloomed that year and I dead headed the heads and kept the seeds. Again this year, I just threw the seeds on the ground, The ground was rocky and hard but they grew. To me, they are very hardy and will grow almost any where. I love these flowers as they very in colors and need very little care. I hand spread the seeds and transplant when they are about 4-6 inches tall. Very few die off after transplanting them. I hope every one else has good luck as I have had.
