Knapweed, Common (Centaurea nigra) Seeds

Produces a deep maroon flower head crowned with thistle-like florets of pink and purple, with dashes of a deep reddish-black. Don’t let its prickly appearance fool you- it’s an exceptionally hardy plant, but it has a softer side as a favourite of butterflies and bees!
