- TimRated 5 out of 5 starsJul 22, 2026Very Happy
My first time growing Zinnias and I just happened to see these seeds in my local hardware store. Started them the beginning of April in peat pots with grow lights. Planted them mid May (Northern Ohio). They really took off when it got hot and humid and are producing beautiful big blooms of all colors and styles. They're spectacular!
I really got lucky because I didn't research the seeds at all and just bought them on impulse. Now I know they are quality and will be purchasing again next year.

Stunning blooms and an amazing palette of color to add to the yard this year. They seem to be surviving a hot, dry climate just fine and blooming prolifically along the way. Couldn’t be happier with these, will definitely be growing again next year.

This was my first year gardening. I had one planter box of zinnias where I used a combo of peppermint sticks and California giants. Turned out beautiful!
