About Field scabious
Knautia arvensis, commonly known as Field Scabious or Blue Buttons, is a beautiful perennial herbaceous plant native to Europe, valued for its showy purple or bluish button-shaped flowers. Its tall, branched stems and lobed leaves give it a wild and elegant appearance. It is ideal for cottage gardens, naturalized meadows, and roadside borders, attracting pollinators such as bees and butterflies.
Native range
Temperate Europe and Western Asia
Care tips
It prefers full sun to light partial shade for abundant flowering. Watering should be moderate, allowing the substrate to dry slightly between waterings, as it tolerates dry periods well once established. It adapts to a wide range of soils but prefers well-drained and not overly rich ones. A common mistake is over-fertilization, which can lead to excessive foliage growth at the expense of flowering.
