Another SOS for you planty people out there.
This has invaded my tiny front garden.
It smothers everything, and provides excellent cover for snails, the other great enemy.
It has tiny bulbs, and slender strap-like leaves.
It also leaves your hands smelling slightly but persistently of chives when it's pulled out to allow the tulips and pansies to survive.
Information and advice welcome!
Thank you for your thoughts so far. Here's an update.
Above is the wild garlic that is so plentiful in the Dene, though not yet in flower. It smells unmistakably of - yes, garlic.
And this is the onion weed flower. It smells of chives, according to the many Australian websites that bring despair to the gardener or farmer seeking to eradicate it without the use of Agent Orange.
I don't think my alien invader is either of those rather pretty plants, although it may be related, but this I know: it is impossible to get rid of!
Next day: Many thanks to Rattling On, who correctly identified it as Allium Paradoxum (Few-flowered garlic) and gave me this link:
Hurrah! Now to discover how to reduce its vigour and curb its Mongol Hordes tendencies.....
