Why do plants have green leaves and not red?

For some reason, despite being able to do so for every other question I have come across (including others posted just before) I am unable to edit this post (or even to re-tag it). Does anyone have any suggestions as to why this would be?

Also, can someone from the community who isn't having problems re-tag the post as appropriate?

I'm pretty sure that means there is an existing suggested edit on that post, you can't submit a second edit then.
