Brighton & Hove Basks in Blooming Beauty of Common Knapweed
Brighton & Hove is turning heads this July with a colourful celebration of the common knapweed, a wildflower that’s brightening up the city’s summer scenes. Known also as Centaurea nigra or black knapweed, this striking bloom flaunts pink-purple heads that can soar up to a metre tall.
From Parks to Roadside Verges: Knapweed Everywhere
July’s spotlight flower is part of a local monthly series highlighting native plants. The common knapweed pumps vibrant colour into Brighton’s grasslands, chalk downlands, woodlands, clifftops, lawns, and roadside verges from June through September. No corner of the city escapes its summer splash.
Top Nectar Source for Buzzing Wildlife
This isn’t just a pretty flower. Common knapweed is a vital lifeline for pollinators, ranking among the UK’s top five nectar-producing plants. Its nectar feast attracts a bustling crowd of hoverflies, beetles, bees, butterflies, and moths. Butterfly fans can spot favourites like common blues, marbled whites, meadow browns, and dark green fritillaries sipping from its petals.
Experts Praise Knapweed’s Role in Urban Wildlife
“Many plants we see as weeds play a crucial role for biodiversity by providing food and shelter for insects, birds, amphibians, reptiles, and mammals – linking the food web together,” said Cheyenne Plant, Sustainability Officer at Brighton & Hove City Council.
“These plants are perfectly adapted to live in our urban landscapes on our chalky soils and can help other plants thrive by fixing nutritional imbalances in the soil. Common knapweed is a great example. It’s a hardy species rich in nectar and pollen, which forms an important part of our natural ecosystem here in Brighton & Hove.”
Visitors and locals alike are urged to take a moment this summer to admire the common knapweed’s charm and appreciate its critical role in keeping Brighton & Hove buzzingly beautiful and bursting with biodiversity.
