I would like to have a very clear summary on the poem "A Contemplation Upon Flowers" written by Henry King"Brave flower that i could gallant it...

A summary, of course, is just a summing up of what the
poem says, written in your own words.  I'll give you the basics of the content of Henry
King's, "A Contemplation Upon Flowers," and let you fill in the details.  That's your
job--I'll just make sure you understand
it. 

Stanza one centers on the
characteristics of flowers.  They are gallant, humble, etc., and they return to the
earth (figuratively, they die every winter--but this isn't revealed until later) after
putting on a show. 

Stanza two
switches focus to the speaker:  he would rather it be always spring, so he'd never have
a winter (again, so he'd never die, but this doesn't become clear until later:  winter
is often used as a symbol of death).  He wishes he could go to the earth (his grave),
and look as cheerful, and smile, as the flowers do when they go to their
earth.

In stanza three, the
focus on the speaker in stanza two combines with the focus on the flowers in stanza one,
as the speaker asks the flowers to teach him to not fear death; to teach him that his
breath may sweeten and perfume his death, as the flowers' breath sweetens
theirs. 

In short, the speaker envys the flowers their
ability to face death without the fact of death negatively influencing their
existence. 

The poem depicts the ways that flowers handle
their existence, inspite of impending doom; the failure of the speaker to handle the
same situation as well as the flowers do; and a wishing for the flowers to teach the
speaker.
