គូឆាយ /Garlic chive (Allium tuberosum)

(Allium tuberosum) known as Garlic/Chinese chives, Flat leaf chives is different from Garlic (A. Sativum). A year-round producer. Cut it down to the soil surface and watch it grow.  

Garlic/Chinese chives typically grow taller than common chives and have flat leaves with white flowers. They have a potent garlic-like flavor and aromatic, unlike common onion chives. Chinese/Garlic Chives lacks true bulbs. 

A year-round producer. Cut it down to the soil surface and watch it grow again and again. 

• A tender perennial. I grown in USDA zone 9a year-round with overhead protection in the rainy and winter season. It is cold hardy from USDA zone 3 and above. 

Allium chinensis (Chinese Garlic Chives or Rakkyo)

There are three species of Allium that come to mind, under the name of Garlic Chives; Allium ramosum, Allium chinensis and, most commonly, Allium tuberosum. On a trip to Guizhou, China in 2012, I noticed a number of Alliums being sold in the market looking like spring onions (A. fistulosum). It later proved that these were in fact Allium chinensis. I had never seen these being grown in the UK. It seemed that this was the Garlic Chive of choice for this part of China. I again found them growing in Nagaland a couple of years later. Here the villagers used to hang them under their eaves, in bunches. This helped to preserve them over the winter, for eating and replanting. In Japan it is used to make a delicious pickle.
