A bit like the sorrel plant, in the sense that this is another one of those just plant it and your pretty much sorted for life in this department. A member of the Allium or Onion [alliaceae/ lillaceae] family – the same family that gave you wild garlic, the supermarket garlic bulb and these really beautiful bulbs.
I got a wee clump from a riend of mine some time ago and they have just multiplied themselves over the years. Some recommend that they are grown from seed – and whilst I have done that this season – my recommendation is that you pop your head over your neighbours wall and ask them for a clump. Lift he clump up and like knotted hairjust rip a section out of it and replant.
When I have too much I pop them in the freezer just after harvesting. As a by the way it doesn’t matter if they are flowering or not from your salad point of view. That said from a get the most out of the plant perspective I prefer they don’t go into flower. Mainly as I want the plants energy to go into producing green leaves rather than seed.
Noted as being a bulbous perennial with short rhizomes grown for its edible, cylindrical, hollow dark green leaves that can grow up to 14″ long. Its umbels can be up to 1″ wide whilst its flowers can grow up to 30 bell shaped purple flowers. The plant itself can grow up 24″ tall and 2″ wide.
