MagJo Naturals European Lavender Flowers (Extra Grade) - 100% Raw From Europe - 2 pounds

What species of Lavender is this?

On the package it says "non irradiated". Is there any version I can get that is irradiated and thus safer?

I want to make sachets for daughters wedding. Will need to make at least 120 small bags. Would you know how many bags of lavender I would need?

Is this food grade? I purchased to bake with.
