Love is like a flower

[Brownlie]

Drought has swept through all the land -- All the land does not need "all," it only serves the meter. 
We wistfully reminisce of the rains of last year; -the meter may be off here. Also, too many ofs in this line.
The budding romance it had so furnished -- In this context the word romance makes me think of the genre. However, that is not really a problem to me. Yet, in my opinion, you have to justify a phrase like "budding romance" with your content. Also the syntax seems a little iffy in this line.
And together shed a sorrowful tear

Passion once held us together
And together we stayed
And though, love, we said it’d never,-- I guess "love" is being used as a noun here to refer to a person. I sort of like the swerving commas and misdirection here. However, that could very well be just me. 
Passion mercilessly strayed 

So just as summer follows autumn -- Normally winter follows autumn, and then you've got the death and whatnot. 
All things must come to an end
I hope that though you are no longer my lover
You will stay and remain my friend -- This seems cheesy, but it doesn't seem like a bad message or complete bullshit.

So there is no need to weep
Nor is there to cry
Love is like a beautiful flower
Even the most beautiful kinds die

I re-wrote this because I originally intended my original poem to be about a poem at the twilight of their relationship, breaking up mutually, but I changed the theme and it got a negative response. So, hopefully, this re-write gets a better one. Thanks!

This is not so bad in my opinion. I guess I would suggest that you make this poem more original. Maybe the themes presented here are too general. Thanks for posting it was fun.
