Scientific Name: Allium x proliferum English Name: Tree or Egyptian Onion Swedish Name: Luftlök
As opposed to the common onion (Allium cepa), the Tree Onion produces little bulblets instead of flowers at the top of its stalks. It is a hybrid species, between the A. cepa and A. fistulosum (Welsh Onion).
The Tree Onion cannot be found in the wild in Sweden, but has been cultivated for a long time. It's believed to have medicinal effects, such as helping digestion, curing insomnia and other sleeping problems, and increasing immunity to the common cold.
