A Small Flower

If you are trying to write a poem, you must begin a new sentence on each new line.  I am assuming that it is a poem because the styles suggests one.

A tiny little flower rose grew in the autumn.

Then the winter have came.

The flower died.

A tiny little flower rose grew in the autumn.

Then the winter have came.

Why is that flower still alive?

(Suggestions and corrections please).

I would use the word "wee" instead of "tiny" if this is a poem.
