How to grow scabious
Discover all you need to know about growing scabious, in our practical Grow Guide.
Scabious is a summer flowering annual or perennial plant. It's sometimes known as the pincushion flower for its pretty blooms.
Although a meadow flower, scabious look as happy in manicured borders, cottage gardens or gravel gardens as in a wildflower mix. They come in a wide range of colours, from white through blue to darkest burgundy. Scabious makes an excellent 'filler', looking good planted among grasses or mixed flowering perennials and annuals. The nectar-rich flowers are very attractive to pollinators and the seeds are good for birds. Scabious make lovely cut flowers, too.

Where to plant scabious
Scabious should be grown in full sun, but will tolerate partial shade, in moist but well-drained soil.
How to plant scabious
Sow annual scabious seeds in autumn and over winter under cover. Sow seeds in a tray and pot on seedlings when large enough to handle. Plant out in situ in spring.
Follow our guide to sowing annual seeds.
Many varieties of scabious set seed freely. A single field scabious plant can produce around 2,000 seeds and the seeds can remain in the soil for a number of years. Save seeds from some of your annual plants to sow in autumn. Perennial varieties can be propagated by division, and clumps should be divided every three-to four years in early spring.

Scabious: problem solving
Scabious suffer little from pests and diseases. In hot summers they can be affected by powdery mildew. Remedy this by mulching around plants with well-rotted organic matter, which helps seal in moisture around the roots.
Caring for scabious
Some taller scabious plants may need staking. Deadhead plants regularly to encourage more flowers and extend the season. In autumn you can collect seed and cut plants back, or leave seedheads in place for the birds.
