What's the meaning of this? i grew a flower that can’t be bloomed in a dream that can’t come true.

My interpretation of this is that the author was hoping for something futile - they 'grew a flower' (put effort or hopes toward) that can't be bloomed (is pointless or futile, will not produce anything) that can't come true (their effort/hope is just a hopeful dream). Basically, the author hoped for something that was not possible.

what kind question

this is a good question! i'll do some research and come back when i have the answer!
