I posted a murky photo of Ramsons (Allium ursinum) aka Wild Garlic in my entry concerning woodland wildflowers on 12th. April. They thrive in full and partial shade in damp soil but here is a clearer image.
 These were purchased as bulbs and I have them growing outside the kitchen door. Appropriately the leaves and flowers do add a strong garlicky taste when used as an ingredient. Then again I see some veined/marbled leaves of Arum italicum growing among them which are toxic so the moral of the tale is: be careful what you pick!
