Blood lime
From Wikipedia, the free encyclopedia
Blood limes are a hybrid citrus fruit developed by the CSIRO project to investigate salt-resistant crops. While the limes proved unsuitable for high-salt conditions, they have seen some commercial development; the first commercial crop appeared in markets in Australia in July 2004, and are under consideration for export.
The blood lime is smaller than most limes, approximately 4 cm long by 2 cm diameter, and somewhat sweeter than the standard.
