The main thing I don't like about hibiscus flowers is the red eye. It's not that it's ugly, it's just so commonplace with lighter colored hibiscuses--and it reminds me of Rose of Sharon, which are even more common here.

Blue River II is named after the Blue River in Oklahoma where its parent plant was found.
