Updated 9/27/24: Taiwanese Bunching Onion is one of my favorite and must have Asian perennial edible in my garden. Since I am selling the seeds and live potted herb, I needed to create a documentary to guide my buyers how to grow and take care of this herb. Bunching onion in general grows easily from seeds with high germination rate too. The only downside is that growing from seeds take a long time than other vegetables and herbs from my experiences. I rather buy a pot of mature bunching onion and then propagate through splitting up the clump.

My kids and I detest the raw smell and taste of regular scallions. Taiwanese Bunching Onions (TBO) are similar yet different. TBO is perennial, low maintenance, doesn’t bolt quickly like scallions, and great in Asian stir fry and soups as it has a natural sweetness, firmer texture that holds its shape well, and has none of that unpleasant raw scallion smell when needed to serve as raw. The leaves are hollow like regular scallions but it’s much smaller and narrower.

9/27/24: You can sow seeds in 4-inch pots or in 1-gallon size pots. Growing bunching onions from seeds takes a much longer time. I prefer starting from an established rooted clump and separate the baby plants to grow more. So in each of these 5-inch deep square pots, I make five little holes about half an inch deep. Then I sprinkle in about six seeds per hole. Each pot will eventually have at least 25-30 seedlings growing. Now I will update this documentary when I seeds sprouted. I have been selling potted Taiwanese Bunching Onions for $5 to $15 per pot depending on pot and plant size.

Taiwanese Bunching Onion grows well in the ground, in raised beds, and in pots with organic well draining soil.

Here is my mature TBO in pots on my vertical garden trellises.
