This is the day of the Qixi Festival (or Qiqiao Festival), a Chinese holiday that celebrates romance, comparable to Valentine's Day in the West. It's also called the Night of Sevens because it's on the seventh day of the seventh month of the Chinese calendar, so the Rose of the Day is Seven Seas.
If you can find this rose anywhere, I urge you to try it out. It's a Harkness floribunda with beautiful blooms.
