Style: Zinnia Dahlia
This package had more than the pkg that was supposed to have 4000, but they are coming up slowly. It is dry here, I have been watering , just enough to get the ground wet and they are scattered, but some are coming up. I also watered the space supposedly where i spread seeds from the supposedly 4000 seeds pkg. They are not coming up as much!

3 days and already sprouting
Style: Zinnia Dahlia, Style: Zinnia Dahlia
I planted these seeds three days ago. They’ve had pure sun these last three days with water that I’ve given them and they’re already starting to sprout. I could not recommend these more if I tried.

Didn’t get a review on the garlic powder
Style: Zinnia Dahlia
The seeds were okay but the garlic powder that I ordered was smaller than usual is a case of bait and switch

Beautiful and vibrant blooms
Style: Zinnia Dahlia, Style: Zinnia Dahlia
This is the first time we planted Zinnias in our garden. Seemed so easy and worry free. It took 2.5 months from the time we planted the seeds to seeing the first blooms. It's now been about 3 months and the plants are in full bloom. The flowers came out in many vibrant colors! The seed packets contained a nice surprise since you don't know exactly what colors the flowers will be. Looks like it will continue blooming for a few more months with a little caring, like constant watering and deadheading. We definitely plan to capture the seeds so we can enjoy the flowers again.

My favorite flower to grow!
Style: Zinnia Dahlia
I love my zinnia flowers!!! I had nearly 100% of these seeds sprout right up!!! (I plant a lot of seeds, and that's not very common)! I can't wait for these beauties to grow, so far they're looking healthy
