A superb, statuesque feature plant

This grand native thistle can stand upwards of 8ft once fully developed. The biennial will form a dense rosette in its maiden year, felted with white down and spiny foliage. In the second year, the towering flower stem erupts from a base of large, silver, acanthus-like leaves, topped with a candelabra of mauve flowers that bees will adore.

On occasion we may need to send you an alternative variety to the one shown, which will be selected by our growing team to ensure its suitability. It will be of equal or greater value to the original. Please contact our customer service team if there are any problems.
