Flowers provide nectar, which is food for insects such as butterflies and bees; leaves, for caterpillars and beetles to hide in and eat; hollow stems for insects to hibernate in; night scent, which attracts moths (which attract bats); and seeds, a source of food for birds throughout the winter.
Many of our native creatures are also predators of garden pests. Did you know that a ground beetle eats slugs? And a family of blue tits can eat 100,000 aphids a year? Natural pest control is an essential aspect of organic gardening.
Below is a selection of useful flowering plants - including weeds, grasses, and wildflowers - to attract a diversity of wildlife to your garden. Most are native. Some, such as Michaelmas Daisy and Poached Egg plant, are non-native but easy to grow, and provide useful food early and late in the year. See also How to grow Flowers the organic way, which includes a helpful guide to making a wildflower area.
Coltsfoot, Tussilago farfara. Native. Perennial weed.
Bright yellow, early spring flowering, dandelion-like flowers. Seeds are loved by birds. It is worth keeping a few of these weeds, but their deep rooting rhizomes can become troublesome.
Grows in most soils.
Cornflower, Centaurea cyanus. Native. Annual
Beautiful blue flowers in summer attract hoverflies and parasitic wasps (see Beneficial Insects). Seeds are loved by birds. Needs full sun.
Grows in most soils preferring neutral to acid.
Cowslip, Primula veris. Native. Perennial
Delicate yellow flowers appear in the spring, popular with bees. Foliage provides food for butterflies such as the Duke of Burgundy Fritillary. Sun/partial shade.
Prefers neutral to alkaline soils.
Cranesbill, Geranium pratense. Native. Perennial
Blue/purple flowers in the summer. Foliage is food for butterfly larvae such as Brown Argus.
Prefers rich, moisture-retentive soil.
Hemp agrimony, Eupatorium cannabinum. Native. Perennial
Pale mauve flowers are attractive to many insects, and birds.
Grows in damp ground, are especially useful for growing on banks of ponds and streams.

Tall-growing plant with pale yellow flowers, highly perfumed at night. Seeds are attractive to birds, flowers to night moths.
Grows in most soils.
Fennel, Foeniculum vulgare. Native. Perennial
