The onions of this variety have bulbs with flat base and are spherical. The other characteristics which make them unique are their deep scarlet red colour, anthocyanin, phenols and high pungency. They are also known to contain higher levels of protein, phosphorus, iron and carotene.[1]
The ideal conditions for growing rose onion are: soil with pH between 6.5 and 7, atmospheric humidity of 70 to 75% and average temperature of 25 °C to 30 °C. As these conditions are found around the Bangalore region, the variety is grown exclusively there.[1]
The pungent property of these onions make them suitable to be used in pickles.
