I've been meaning to write my own but, I never had the motivation to continue. But, from what I was daydreaming of, I'll tell about my fanspecies.
It's as of these flower-people, where their mating rituals are mostly the same as our flowers. A mediator has to be present to basically watch both of them do it. (I know, it's stupid and ridiculous, as it should be.)
They would all have different scents, floral desires. Whether it be Lilypadians, Roseians. I think that that sort of species would be an interesting change to what everyone thinks of space aliens looks like.
For all I know, I never continued with it, I might some day. But, I just think that the whole concept of flower people would be really funny and dorky.

And here's an example on what they'd look on my web comic.
