When harvesting the tree onion (Allium cepa proliferum), you don’t cut off the bulb, as you would with other onions; instead you pluck off its little bulblets. Originally from Southern Europe and Egypt, its green-blue stems, between 50 and 80 cm in height, are permanent and are somewhat reminiscent of chives.

post philately has issued a book of self-adhesive stamps showing the diversity of luxembourg's mushrooms.
there are over 2,500 different species of mushroom in the grand duchy of luxembourg. the humid and temperate climate offers the perfect conditions for mushrooms to prosper in the forests.
they are essential to the ecosystem as they recycle organic waste matter in the forests. they also help the plants and trees to absorb the minerals that they require.
