Not blue at all, I'm afraid, but a more purplish hued form of the more familiar deepest pink Cirsium rivulare 'Atropurpureum'. A fine plant, adding height to the midsummer border. Loved by bees. Hardy. To 1.5m
I spent ages browsing colour-naming sites to try and pin down the exact difference between these two colours. Best if you take a look at the pictures yourself and decide!
Sorry, this plant is out of stock
