Centaurea nigra

Centaurea nigra
Common name knapweed
Family asteraceae
Life cycle perennial
Flowers purple (summer)
Size 2-3'
Light sun
Cultural notes ordinary garden soil
From seed reseeds in our garden

Bushy plants with purple bachelor's buttons-type flowers. The close-up photo is typical - it's hard to find a flower without some insect sipping the nectar when knapweed is in flower. Not the most refined plant, but nice in a looser area of the garden (that is, most areas of our garden :-)


This plant used to grow in our garden, but it slipped away...
