Much smaller, but also popular with insects, the Common Centaury - a member of the Gentian family - is delightful to us but provides food to many smaller insects.
The Derbyshire Wildlife Trust have sown several areas of Shipley Park, with a mixture of wildflowers specifically for producing seeds to feed the birds in winter.
These colourful meadows are full of Corn marigolds, Cornflowers, Chicory, various members of the Pea family and a host of others. The benefits are twofold. They will of course, provide seeds for the birds, but not until the insects have done their bit and pollinated them. What you might call a 'win-win situation.'
