- Tiffany T.Verified BuyerRated 1 out of 5 stars4/22/26Incredibly low germination
Planted the entire pack and one came up. Usually Belstar is my go-to in my climate and I end up with buckets of broccoli, but I've always bought the seeds somewhere else. Lesson learned.

Thank you for taking the time to leave a review. We’ve reached out via email to help. Quality is very important to us, and all of our seeds are regularly third-party tested to ensure strong germination rates. In many cases, germination issues are related to environmental factors like moisture, temperature, or planting depth. We appreciate your feedback and support — keep on growing 🌻

I planted late and this was one of only 2 broccoli varieties that didn't bolt or get overtaken by pests before I could eat it!

Thank you so much for sharing your experience with our Belstar Broccoli Seeds! We're absolutely thrilled to hear that Belstar came through for you even with that late planting - that heat tolerance really is one of its standout features! It's so frustrating when other varieties bolt or get overwhelmed by pests before you can enjoy your harvest, so we love that Belstar proved to be such a reliable performer in challenging conditions. Keep on growing 🌻️
- Cheryl D.TX, United StatesRated 5 out of 5 stars5/25/25Excellent Germination and Production
These started off slowly, but are really making good progress now. I put them out as almost strands to make sure to get them started in relatively cool weather, and fully expected them to fail. I’ve heard it’s difficult to grow broccoli from seed. Thee are thriving and I can’t wait to see how they finish!
