Do buy!!!

This is not a fake review. These zinnias made huge double blooms in orange yellow, pink red, white and purple!! I recommend and they only took 7 weeks for the first flower to open. A must buy!!

I buy seeds from The Climbing Fig on and off through the year. Their seeds are really good, always matching their product description. I know when I sow them very soon I shall have strong healthy plants. I can rely on them. Always.
