Borage is an annual herb steming from Syria, but naturalized throughout the Mediterranean region together with Asia Minor, Europe, North Africa, and South America.The flowers - often blue in color but sometimes observed pink - are complete, perfect with five narrow, triangular-cuspidal petals. Borage grows to a height of 60-100 cm (2.0-3.3 ft), and is hairy pervade the stems and leaves that are alternate, simple, and 5-15 cm (2.0-5.9 in) long. 
Borage is traditionally used as an ornament in the Pimms Cup cocktail, but is often substituted by cucumber if not acquirable.
It is also used for companion planting.If planted close to tomato plants, it is said that borage not only improves their growth but also makes them taste better and repulses the tomato hornworm.
