CENTAUREA NIGRA

Today I removed Verbena bonariensis from my perennial border and then I uprooted Centaurea nigra.  While the former plant shot up into the air, was much wider and taller than the label described, and looked odd amid its neighbouring plants, Centaurea nigra looked downright ugly.  The leaves were dull and the flowers small.  It required staking and, if I had staked it, it would have been much taller than the label described.

The labels says:


Centaurea nigra is a clump forming deciduous perennial with thistle like pink flowers during summer.  It grows in any well-drained soil in full sun.  It achieves a height of 70cm (28") and spread of 60cm (24"). 


If a plant doesn't look right, it has to go.
