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.

Thank you so much for sharing your experience! What beautiful photos of your Giant Purple Zinnias - what a perfect choice for your first flower growing adventure! It's wonderful to hear that starting them indoors worked so well for your Zone 4 garden. Your description of each flower being a unique work of art with that stunning ultra violet purple color just makes our hearts happy! And we love that they've become such a buzzing hub for bees and butterflies in your garden. Keep on growing 🌻️
