Sweet Annie!!!!

If you, like me, love the smell, texture and look of Sweet Annie, then you can never have enough!  Which is why I grow my own.  Sweet Annie is easy to grow and can get very tall.  I harvest mine when the seeds form, the leaves will appear to be replaced with tiny golden balls. 
I've cut a huge bunch this morning, it is now all in containers filled with glycerin and water.
If you choose to air dry your Sweet Annie, it will eventually fade to a brownish color and will be dry and shatter easily....making a nice mess.
By preserving in the glycerin, it retains a green color and a "softness".  And best part is, it still smells wonderful!
I mix 3 parts of water with 1 part of glycerin in a glass container and immerse the freshly cut stems.  Don't overcrowd the stems.  In approx. 1 week, I remove the sweet annie and if there is anymore water in the container, I allow the cut ends to dry.
Purchasing glycerin can be costly if you are not drying ALOT of sweet annie.  However, if you want to give it a whirl, you can purchase a small bottle in Walmart for under $5.00 in the first aid section.
Right now, I have many glass containers of sweet annie scattered around my house, preserving away!!
