## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality
*by R***N on November 6, 2023*

These seeds were quality. Big beautiful sunflowers like I remember dad growing when I was a child.

### ⭐⭐⭐⭐⭐ Mammoth sunflowers
*by J***I on March 13, 2014*

This is my first time growing sunflower seeds and my husband and I chose the mammoth heirloom for a start.. I put them in an egg carton with some potting soil and whammo! Within a few days they were already sprouting up and out like they were on fire.. Needless to say I transplanted them after 2 weeks and they have already started they're second set of leaves. I'm getting ready to put them in the ground and I can't wait to see how they do.. I will write another update soon

### ⭐⭐⭐ Jury still out.
*by D***E on December 28, 2023*

Only had two of the many that I planted came up. But they were very impressive. Looking forward to next year.
