Summary
Centaurea triumfettii, commonly known as Squarrose Knapweed, is an herbaceous perennial plant native to the Mediterranean region, including southern Europe and northern Africa. It typically grows to a height of 12-24 inches and features undivided, narrow-lanceolate leaves. The plant is distinguished by its composite flower heads, which bloom from May until August, showcasing bright purple inner flowers surrounded by azure blue or deep mauve bracts that resemble petals. The flowers are moderately showy and attract pollinators such as bees and butterflies.
Squarrose Knapweed is valued for its vibrant flower colors and is often used in wildflower gardens, naturalized areas, and as a part of pollinator-friendly plantings. It is adaptable to a variety of soil types, provided they are well-drained, and it thrives in full sun to part shade. Gardeners should manage its growth to prevent it from outcompeting native vegetation.CC BY-SA 4.0
