Wow, @scrawly! Your art gets more and more amazing! Such beautiful and delicate girl! ^.^ And the sunflowers are one of my favorites.
Can't wait for the next flower. ^.^
As for your question - I don't know about ugly flowers, but I find some of them rather unique/funny. Like this for example:

It's called Antirrhinum, also known as "dragon flowers" or "snapdragons". XD When you press it open, it resembles the face of a dragon.

Hehehe what a cute flower. It looks more like a friendly spirit creature than a dragon, though I can see why they call it the snapdragons.
Yaassss, we're both are team sunflowers! ᕦ༼ ͡° ͜ ͝° ༽ᕤ
Thank you <3.
