I've been experimenting with bunching onions to learn when is best to plant them as we live in the "intermediate" or mid-section of the US. I have yet to have success with bulb onions getting large enough to hold in the palm of your hand, so that leaves green bunching onions to try.
Of the three bunching onions I tried sowing directly this late summer/early fall (Evergreen Bunching, Southport 404, Lisbon), Evergreen Bunching sprouted the quickest. I also sowed Evergreen Bunching in a pot, which most every seed sprouted easily and they are currently overwintering in our green house until I can plant them in the garden as soon as we are no longer in the single and teen digits for overnight low temperatures.
One suggestion to get seeds to sprout in garden is to cover newly... read more

Sow from early spring to midsummer. In coastal areas can sow right through the winter. Germinate in 10-21 days. Thin to stand 3in apart when 1-2in high. Does not form bulbs (eat like a "Spring onion").

These are so satisfying to grow, sprout quickly, and are easy to watch as they progress. I have been known to harvest one or two (or three) as early as 3 weeks. At that age they are tiny but just as tasty!
