Greeny-black ovaries in the centre of each floret provide the reason for the name, though the suggestion of blackness somehow does not sit so well on what is otherwise a creamy white flower! The flower head shape is less rounded and more flattened and they are easily grown in sunny well-drained soils with a dry summer rest.
Plant with 3-4" (8-10cm) of soil over the Allium nigrum bulb in a sunny well drained soil about 4-6" (10-15 cm) apart where they will get a dry summer rest. Dot them about informally, perhaps with purple Gladioli or Cow parsley?
Height 24" (60cm)
