No it doesn't...
What rhymes with spot, rot, tw*t
but as far as I can tell, it doesn't rhyme with orange.
Nothing is a true rhyme with orange. BUT your can have a whole word rhyme or a part word rhyme. The part word can be the start of the word or the ending just so long as you follow the pattern all the way through the poem there should be no problem. As for finding a rhyme for orange. You can shout out loud safely with the word Lozenge.
