What are some good Yuri anime to watch?

Aoi Hana

It's a slow paced one (even though it's only 11 episodes) but it's really sweet. And I really like the op.

There's also Sasameki Koto but the anime was done while the manga was still ongoing so it doesn't really wrap up. 

Kashimashi: Girl Meets Girl is kind of weird but some enjoy it.

Simoun is also a weird kind of yuri series, and by weird I mean it throws a lot of terminology at you early on. 

Also I'm just going to toss in YuruYuri because it counts.
