Sweet everlasting (Pseudognaphalium obtusifolium) is one of those weedy plants, growing throughout central and eastern North America, which we tend to notice only as it begins to bloom.

Its flowers may seem a bit strange since they don't look like they "open up" as we might expect.  Instead the disk flowers for each flower head remain hidden within the white bracts.

Watch this video of one year in the life of Sweet everlasting (Pseudognaphalium obtusifolium) to see its woolly (or cottony) covering of the stem and leaves, to learn about its fragrant identifying characteristic and to see a close-up view of its tiny seeds.
