- Cheryl R.Verified BuyerRated 3 out of 5 stars8/22/26Not As USual
I always order Cactus Zinnia Seeds from Botanical Interests. This year, many of the blooms looked like regular Zinnia blooms. I have never had them look like anything but the photo on the package.

- GraceVerified BuyerRated 4 out of 5 stars7/5/26My favorite zinnias
I buy these seeds every year, but this year I bought 4 bags and only half of them are cactus. Iām a little disappointed, I was expecting to have all cactus zinnias in my garden. I hope next year you can collect the correct seeds.

We truly appreciate your patience and hope next year's harvest gives you exactly the beautiful cactus zinnias you're looking for. Keep on growing š»ļø
- Janet D.Verified BuyerRated 5 out of 5 stars6/6/26Delighted with Seedlings
I planted the Zinnia Seeds directly to the garden soil. Amazingly they sprouted in three days!! Our Spring 2026 provided the perfect weather needed to nourish their growth. The "seedlings" are healthy and growing very fast. I recommend these as they are so easy to plant and are growing taller by the day.
BIBotanical Interests6/10/26Hey Janet,
What an amazing three-day germination rate with our Cactus Flower Blend Zinnia Seeds! We love hearing about those healthy, fast-growing seedlings taking off so quickly in your garden. Direct sowing can be so rewarding when the conditions are just right like they were for you this spring. It sounds like you're going to have some gorgeous blooms coming your way! Thanks for sharing your Cactus Flower Blend zinnia success with us! Keep on growing š»ļø
