The Zonta yellow rose symbolizes friendship, joy, and
the mission of Zonta International
to improve the lives of women worldwide.

The Zonta yellow rose, also known as the Hartanna, was introduced at the 1984 Zonta International Convention in Sydney, Australia. It was developed by the renowned nursery R. Harkness & Co. Ltd. as a living symbol of Zonta International, thanks to the efforts of Zontians like Valerie Webster and Maureen Ros.
This rose has become a significant emblem for Zonta, representing the organization’s commitment to women’s rights and empowerment. Since 1999, the yellow rose has been celebrated on Zonta Rose Day, which coincides with International Women’s Day on March 8. On this day, Zontians worldwide distribute yellow roses or items featuring the rose’s image to raise awareness about issues affecting women.
The Zonta yellow rose is characterized by its bright yellow blooms, which are produced in large sprays. Each flower has a light, pleasant fragrance and is known for its hardiness and ease of growth, reaching an average height of about 1.2 meters. The rose is also recognized for its long-lasting blooms, whether on the bush or as cut flowers.
