allium cepa

A sale on onions in India this week by deal-of-the-day website Groupon was so popular that it crashed Groupon's Indian website.

Onions have a long played a symbolic role in Indian politics. In January 1980, the Indian National Congress Party leader Indira Gandhi returned to power, campaigning against rising onion prices. At rallies she waved huge strings of onions and said a government has no right to govern if it cannot control onion costs.
