Aoi Hana (青い花) is a yuri manga by Shimura Takako. Original run: 2004–2013. There is also a 2009 TV anime adaptation.
The Japanese manga tankoubon release covers also give an English title, Sweet Blue Flowers.
JManga published at least parts of the manga series online in official English translation around 2012–2013, but these are probably no more available. An official English-subtitled online version of the anime has been released by Crunchyroll.com.
Themes include lesbian and bisexual adolescence, love and friendship, girls'-school life, and amateur theater.
