Wild Flowers Known and Unknown

We live in the woods.  And as we walk through the woods to garden, mailbox or field we see the seasons unfolding. the wild flowers continue to bloom and plants grow.  Some I recognize and know the names like trillium

and geranium 

and yellow violets.

and ferns

Then there are some I see every year but I do not know their names - this one

and these spiky flowers

and these lovely pendulous flowers

I feel odd as I walk listening and looking and enjoying.  But often I cannot tell people names of the birds singing or plants.
