This is my first year growing any flowers, I’ve been growing veg for a decade. I was worried it would be difficult, but these Zinnias were so easy! I started mine indoors because I’m Zone 4 and have a lot of birds trying to eat seeds I direct sew. Four seedlings turned into quite a few bushing plants with lots of flowers. Each one looks unique and the ultra violet purple color is out of this word. They are constantly covered in bees and butterflies.

The seeds that I have purchased from BI are my favorite seeds. This was my first year, trying flowers, and it felt almost full proof with these seeds. I bought a variety of zinnias and all of them turned out beautiful.
