From the Downy website, it seems the scent is a mix of creamy jasmine, lily-of-the-valley, and sweet rose and the scent combination is called Honey Flower. It can be used like a regular fabric softener.
If you create an account at PG Everywhere, you can request a bunch of sample for P&G products as well as request several coupons. P&G provides samples at specific intervals and so you can sign up for all the available samples and you only need a couple of minutes for processing the request. This is a lot more efficient than signing up for each sample individually.
I just requested mine and the sample is still available! I also got samples for a bunch of other P&G products, plus coupons!
