What color is the claw onion unearthed in February?

Claw onions unearthed in February have golden leaves and white stems. Pig excrement bean, also known as Louzi onion, is a variety of onion, with long conical leaves and hollow. The pseudostem is short, partially white when buried, and wrapped in brown-red onion skin after aging. On the terminal bud of the onion plant, the onion grows out again, which looks like a dragon's paw. Some plants can grow three layers of stems and produce three layers of shallots, so they are called "Lou onions". Varieties introduced from the northwest have aerial bulbs and a few floral organs at the top of the flower stem, which can't bear fruit. Shantou likes cold climate and has strong cold tolerance. The underground bulbs of Allium chinense cultivated in the north can safely overwinter in the open air at extremely low temperature below zero degrees Celsius.
