The Tainan District Agricultural Improvement Farm in Taiwan has developed a new variety of purple asparagus, named 'Tainan No. 5', by breeding the 'Purple Passion' variety with Taiwanese green asparagus. This new variety is heat-resistant, high-yielding, and more appealing in appearance than previous purple asparagus varieties. It is expected to boost the fresh asparagus market. The breeding process took eight years due to the long growth time and specific requirements of asparagus. The variety is also more adaptable to the Taiwanese environment than previous purple asparagus. However, it requires careful prevention of disease and pests, and specific temperature and sunshine conditions for optimal growth and appearance.
