- Mary L. W.Verified BuyerRated 5 out of 5 stars6/24/26Really and truly fireballs!
These seeds were up in four days and have grown quickly into robust plants. Contrast Botanical Interest seeds with another well-known, less expensive brand that did not come up until I put them into a seed starting frame with a clear plastic lid (which they also sell ) That competitor's seeds have never grown into anything robust, and have not bloomed yet, and were planted at about the same time. The first photo here is of a plant that is from Botanical Interest seeds, that came up volunteer from last year's plant! About the beets, I decided to wait until fall to plant them.
BIBotanical Interests6/25/26Hey Mary,
We're so thrilled to hear about your amazing Fireball Blend Zinnia success! Four days for germination and then growing quickly into robust plants - that's exactly what we love to hear! It's wonderful that you can see such a clear difference in quality compared to other brands, and we really appreciate you sharing that comparison. And how exciting that you even have a volunteer from last year's plant coming back to show off - that's a true testament to how well these Fireballs perform! We hope you get to enjoy lots of beautiful blooms from these robust plants as the season continues. Thanks for sharing your fantastic zinnia experience with us! Keep on growing 🌻️

This was my first time growing the Fireball Blend and they were so easy. They started blooming a few weeks ago and the colors are so, so beautiful.

Love this blend! These flowers have been the highlight of my summer garden, surviving the Phoenix summer in full sun. Only wish I planted more.

I've been growing these zinnias for 2 summers now - they are a tall variety with large blooms. Perfect for large butterflies to land on - they are attractive to many monarch and swallowtail butterflies in my yard. Their red and orange colors are vibrant and they last a long time.
