Big news about a common herb I grow concerns me a bit. Stevia is a natural sweetener. I use it and I think I've mentioned it before here, maybe not. Now that the FDA has approved Stevia for soft drink production etc, you can pretty much bet it will soon become impossible to buy seed to grow your own. Such is the way of commercial business laws like possessing ginseng without a government issued permit or not being able to sell the roots of plants that grow wild without a government issued permit, not being able to buy seed like Cardamom etc...Things being illegal to grow in some states such as the idiotic ban on Morning Glory's or castor bean comes to mind. Here's something to look at, how often have you noticed celery seed for sale on the racks in the spring?
I'm allergic to bee stings so keeping bees for honey is pretty much out of the question. I simply do not have enough land to grow things such as sugar beets or cane. A substantial part of my cold storage/preps is refined white sugar. I will be cultivating my Stevia again this spring only in larger quantity.
Perhaps it's time to review the seed you've saved and include some herbs you can still get seed for that can help keep you healthy, make you healthy if you are sick and make your food more tasty in general.
