Easy to grow; so cheerful to view

I ordered several packets of seeds from Pinetree, including this Zinnia mix and the Cherry Lime Zinnias. I had never grown zinnias before and this was the perfect year to start - with the high temps and near drought conditions here. I watered well early on to give them a good start, but have not had to continue. They seem indestructible and prolific, and the flowers are so perfect and cheerily colored!. I will definitely be ordering these again yearly from now on.

Great germinate rate

I tried another seed company and I have gotten better germinate rate from volunteer seed . Yours is 100% as far as I can tell .
