Lilac's... definitely smells like them !
OMG, the scent stays with this, I have them in a jardiniere on my lanai, where it is hot and humid right now and if I go out and sit at the table I can smell the lilacs.  I love the scent and I bought a second bag because I love it so much !!  I do not like scented candles but I sure love this product.
