Centaurea Macrocephala – Giant Knapweed

Centaurea macrocephala, or Giant Knapweed, is certainly not shy and retiring. This substantial perennial produces impressive golden-yellow, thistle-like flower heads, opening from distinctive rounded brown buds and standing proudly on strong, upright stems.
Growing to around 1-1.5 metres, it is a brilliant choice for adding height and a slightly wild, architectural quality to the middle or back of a sunny border. The bright yellow flowers look particularly striking amongst grasses and other herbaceous perennials, while a group planted together can make a real midsummer feature.
Giant Knapweed is also an excellent cutting plant. Its unusual blooms add texture and character to fresh arrangements, and the flower heads can be dried for longer-lasting displays. Tough, distinctive and refreshingly different, this is a perennial for gardeners who like their plants with plenty of personality.
Supplied in approx. 1 litre containers.
