Logo for Natural Toothpaste (simple, clean, green)

VitaGree

PM working to help a friend with logo design.

Users of natural / holistic / organic products - toothpaste.

Logo must be simple - cheap to print - little to no gradient used.

Logo for natural toothpaste: VitaGree - power of nature-natural toothpaste from organically grown wheatgrass and healing herbs, barriers and minerals which promote dental health.
Developed by San Francisco Holistic Dentist.
Made in USA.
Sample ingredients: wheatgrass, chlorophyll, 12 berries

We are looking for a logo and an idea on how it will look on a tube and the box packaging.

The logo must be must be SIMPLE, clean, MAYBE incorporate wheatgrass.

Owner wants to print it in color but as cheap as possible so gradients don't work too well. He is not a fan of wiggly fonts and doesn't want to see leaves or flowers (only wheatgrass incorporated if it looks clean but SIMPLE).

Assets:
http://www.restbros.com/dev/vitagre…mments.doc – past logo concepts with a few comments
http://www.restbros.com/dev/vitagre…oducts.zip – logos and packaging of similar products

If your logo is the winner, we will work further with you to develop the packaging for an additional cost. Furthermore, you will be given priority in the website contest for the product.

Final logo must be in a fully layered vector form.

I'll add / remove details as I see some submissions.
