History and Origin
The cultivation of Bangalore Rose Onion dates back over a century in the fertile red loamy soils of Bengaluru Urban, Bengaluru Rural, Chikkaballapur, and Kolar districts.
The unique soil composition and semi-arid climate of this region give the onion its signature pinkish-red color and mild flavor.
Historically, this onion was grown by small farming communities for local markets. Over time, its superior quality and aesthetic appeal gained popularity across India and abroad, leading to its GI recognition under “Agricultural Products” (GI No. 178).

They were also historically cultivated in Tumkur, Hassan, Davanagere, Dharwad, and Bagalkot.
Importantly, Bangalore Rose Onions are not cultivated in any other place in India, preserving their regional authenticity and exclusivity.
