Seasonal?

If you type seasonal gifts into google, you're most likely to see everything based around Christmas.
I want to design a product for each season, just so Summer, Autumn and Spring don't feel left out. :)

The Concept.
'Tea is good because it helps relieve stress.'
My product will help relieve stress through scent. Research shows that tea helps, so, I will produce a product containing tea. You cannot drink it. Only smell it. It is extremely compact, and is something which can easily carried around with you.

The Idea.
I will produce a leaf or flower representing each season. I plan to use material which will contain tea with, perhaps, a hint of a scent which also symbolizes the season.
I will ''invent'' a name for my product and design a logo which will appear on the packaging as well as the product.
I want the ''tea bags'' to be packaged individually so they can only be purchased during each season. They all won't be available throughtout the entire year, so I guess you could say they're limited edition.
